CT, MRI, Ultrasound, And X-Ray: To Be Afraid Or Not?

Manifestations of many diseases take us by surprise, change our plans, disturb. On the one hand, the symptoms themselves can scare, and on the other, the need for a diagnosis. CT, MRI, ultrasound, and X-ray - is it harmful or not? And why several - is it possible to do one thing? What do you need to know about the most common methods of medical imaging today? How do they differ from each other? Which diagnostic method is right for you?

ultrasound-and-xray

In the arsenal of modern doctors, there are many diagnostic methods. At the same time, more and more people are talking about overdiagnosis. How does the patient understand that the study is really necessary? In what cases are CT, MRI, ultrasound, and x-rays prescribed?

On overdiagnosis in relation to the patient, we can talk in the case of self-designation. When patients who have some kind of complaints, they prescribe themselves some kind of examination without consulting a doctor- for example, after reading some article on the Internet.

The moment determining the choice of a diagnostic method is the estimated area of ​​damage. For example, if pathology from the pulmonary system is suspected, then the primary method will be radiological. The use of MRI, in this case, is impractical.

Therefore, before undergoing a study, it is better to first see a doctor, and then undergo one or another additional examination by MRI scan centre in New Delhi- both laboratory tests and instrumental diagnostics (ultrasound, CT, etc.). The only way is it possible, on the one hand, to be immediately examined purposefully, and on the other, to avoid unreasonable (often very tangible) material and time costs.

- Each of these research methods has a radiation load on the body?

No, only methods based on x-ray radiation (in particular fluorography, fluoroscopy, and radiography, CT). Ultrasound and MRI do not carry any radiation load, as they are based on other physical phenomena that have nothing to do with radiation.

- Magnetic resonance imaging and computed tomography, ultrasound and x-ray - which of these research methods is the safest, and which is the most informative?

The safest of them is an ultrasound scan, and also, in the absence of contraindications, an MRI. In terms of information, CT and MRI will be the leaders, but each in its “nomination”. For example, to detail the pathology of the lungs, CT is most informative, while when examining the brain- MRI.

- Is it true that to clarify the diagnosis, only one diagnostic method is not enough?

If we talk not only about the methods discussed above but about diagnostics in principle, then most often - yes. Diagnosis is a multi-component process. For example, an ultrasound revealed some kind of formation. To clarify its nature, MRI may be needed. Suppose tomography showed the presence of a tumor. But what kind of tumor is it? To answer this question, a biopsy may be necessary, sometimes even a diagnostic operation.

- If the patient has an alternative between CT and MRI - what to choose?

Again, it depends on what area of ​​the body, organ (s) are planned to be examined. If, for example, we are talking about the head or spine, then an MRI will be preferable. Often you can hear the question of what is the difference between MRI and CT scan cost in Delhi NCR, and which one is better. The basis of CT is the principle of x-ray radiation, and MRI - of the magnetic field. Both methods solve their own range of diagnostic tasks, and, if necessary, complement each other.

Why Is Computed Tomography Important For Diagnosing Diseases Of The Circulation?

Cardiovascular diseases have become one of the main reasons of death in the world. In several countries, according to data from the Ministry of Health, they are the first cause of death among the population. Computed tomography equipment can help doctors establish an early diagnosis to prevent circulatory system pathologies.

What is a CT scan?

A CT scan is a procedure that uses an x-ray source that revolves around a circular structure called Gantry. Each time a complete rotation is performed, a computer constructs a 2D image cut, repeating the process until the desired number of cuts is obtained. In each image cut, the thickness of the tissue to be checked is represented; this thickness can vary between less than 1 millimeter and 10 millimeters depending on the type of equipment used.

The images can rotate in space or see the cuts successively, generating a 3D image showing the skeleton, organs, and tissues of the patient simultaneously. Thanks to this, it will be more precise to locate the point where any anomaly is occurring.

CT scans are used to detect tumors, infections, fractures, hemorrhages, among other pathologies. Despite its versatility in clinical diagnosis, its use should be limited since exposure to X-rays is high (although it does not leave remains in the body after the end of the test). Special care must be taken with children, who are more sensitive to ionizing radiation.

Contrast for a CT

In soft tissues, the ability to retain radiation is variable and, therefore, more complicated to visualize inside. Therefore, contrast media have been developed, which makes these tissues highly visible in a CT scan.

In contrast, media the patient is injected with a substance rich in iodine that circulates to the organs, changing the way they look through the x-rays. In the case of the circulatory system, the contrast will illuminate the blood vessels in search of possible obstructions. It is essential to know contrast CT scan cost in Delhi first.

There are other types of contrasts, such as barium compounds that are used to examine the digestive system.

How can a CT diagnose circulatory diseases?

Angiography performed with computed tomography or Angiotomography (ATC) equipment analyses blood flow in different parts of the body, such as the brain, heart, abdomen, legs, and arms.

CT scan serves not only to assess the proper functioning of blood vessels but also to diagnose diseases related to circulatory problems such as:

  • Alterations in arteries or veins (aneurysms).
  • Atherosclerotic plaques in the arteries.
  • Obstructions in the blood vessels.
  • Congenital disease in the arteries.
  • Ischemic accidents or cerebral hemorrhages.
  • Arterial disease in the blood vessels of the heart.
  • Pulmonary embolism in the arteries etc.

Also, the ATC through computed tomography equipment are used by surgeons to see the result and evolution of an intervention performed or to plan a future surgery using it for example to:

  • Guide in a reconstruction of blood vessels.
  • Evaluate coronary veins after the placement of a pacemaker.
  • Review the efficacy of an angioplasty or stent placement.
  • Evaluate the need for a bypass.
  • Perform a tissue biopsy.

Angiography with computed tomography is a faster, non-invasive type of test that has fewer complications for the patient than is traditionally performed using a catheter.

Using The CT Method (Computed Tomography) In The Diagnosis Of Oncology

To detect the presence of cancer cells in the body, there are several modern methods of examination. One of them is computed tomography. With the help of this instrumental study, it is possible not only to identify oncology, but also to find its individual foci (metastases), as well as other pathological processes.

diagnosis-of-oncology

Metastases quickly spread throughout the body, affecting various parts of it. With the help of CT, one can detect both volumetric neoplasms and the smallest cancers. What is good about this study is that the image transmitted by the tomograph will allow you to examine any type of tissue - from soft to bone.

Why is it important to use computed tomography to diagnose cancer? Because the device will show the formation of any size - up to several millimeters. Thanks to such a detailed diagnosis, the oncologist has a unique opportunity to clarify the diagnosis and prescribe the right treatment. The CT scan price in Delhi varies according to the type of CT scan that is to be conducted.

The effectiveness of computed tomography has been proven in the study of such systems and organs as:

  • Lungs, bronchi;
  • Brain;
  • Pelvic organs;
  • Spine and other parts of the skeleton;
  • Blood vessels;
  • Skin integument, subcutaneous tissue;
  • Abdominal organs;
  • Lymph nodes.

When is computed tomography prescribed?

The CT method is effective in examining most organs and systems of the human body. Indications for examination are many pathological changes. So, it is necessary to carry out:

Brain tomography under the assumption of hemorrhagic stroke, vascular pathologies, neoplasms in the brain and meninges, hematomas (with the specification of their location). If the patient has a history of malformation or vascular aneurysm, CT scan is necessary. Before undergoing a CT scan, it is good to know the CT scan cost in south Delhi first.

  • CT of the head (cranial box) - in case of severe contusion, developmental abnormality, skull fracture, suspected cyst and other formation. The picture will allow the doctor to assess the patient’s condition and help to decide on the need for surgical intervention.
  • Computed tomography of the larynx, nose - if there is concern about the presence of a tumor, chronic sinusitis, and inflammation of the lacrimal flows.
  • Tomography of the lungs - to determine the presence of focal and pathological neoplasms, pneumonia, emphysema, etc.
  • CT of the chest - with suspected pathology in the organs located in the chest cavity: pleura, lungs, bronchi, esophagus, heart, lymph nodes.
  • Computed tomography of the spine - in difficult cases, to clarify the diagnosis. Indications for CT - scoliosis, trauma, osteoporosis, leg pain, intervertebral hernia, damage to the vertebrae and discs, osteochondrosis.
  • Tomography of the abdominal cavity - to determine the presence of cysts and their size, pancreatitis, blood clots, inflammation, appendicitis, fluid accumulation, pathological changes. This examination is indispensable for suspected neoplasms.
  • CT of the joints (shoulder, hip, knee) - to determine the cause of pain in the joint during movement, the accumulation of fluid in it. Such a study is carried out when the patient is suspected of developing arthrosis, arthritis, as well as to determine the degree of pathological changes in the joints.
  • Computer tomography of the genitourinary system - with suspected cancer in the bladder, kidneys.
  • CT of the intestine - to establish the cause of the problems in this organ.
What Are The Causes Of Chest Pain?

Pain in the chest is one of the most important symptoms of a number of diseases of the heart and blood vessels. Chest pains can be caused by pathology not only of the heart, but also of other organs and tissues of the chest, and also caused by diseases of the abdominal organs.

causes-of-chest-pain

Timely differential diagnosis of chest pain requires a doctor with sufficient theoretical knowledge and knowledge of the methods for examining patients at the CT scan centre. Chest pain may appear in a previously healthy person for the first time in their life.

In other cases, the patient develops pains of a different nature than before, and this may be due to the progression of an existing disease or the appearance of its complications.

The most important characteristics for differential diagnosis of chest pain: factors that provoke pain, localization of pain, duration, depth, circumstances of pain relief, as well as some other specific features of the pain syndrome. You should first know the chest CT scan cost in Delhi, before going to have a CT scan.

Provocative factors

When collecting an anamnesis, it is necessary to determine the dependence of the occurrence of pain on various circumstances and situations in which the pain begins to bother the patient or intensifies.

  • With an attack of angina pectoris, pain often occurs during exercise.
  • Pain characteristic of pericarditis occurs with a change in body position and deep breathing.
  • For pleural pain with pneumonia, pneumothorax, pleurisy, a connection with breathing is also characteristic.
  • With peptic ulcer and esophageal reflux, the relationship of pain with food intake (on an empty stomach), time of day (at night), and body position (lying) is important.
  • With esophagospasm, chest pain often occurs during exercise or after a cold drink, but can also be spontaneous.
  • Pain in vertebral hernias is often aggravated by movement of the head and neck and palpation, which is also characteristic of musculoskeletal pain.

 Pain localization

The sternal pain localization characteristic of IHD is also observed in diseases of the esophagus, in case of hyperventilation, and pulmonary hypertension. Against the background of the pathology of the gastrointestinal tract, pains are often localized in the lower part of the sternum and in the epigastrium. Pain with stratified aortic aneurysm often radiates to the back or lumbar region.

The basic principles of medical tactics for acute chest pain

  • With any nature of the pain syndrome, an electrocardiographic study is performed to exclude the most formidable pathology - acute myocardial infarction.
  • Patients who are in doubt about the diagnosis, aged over 40 - 50 years old with intense pain in the chest (even atypical nature of angina pectoris), before the diagnosis is clarified, it is advisable to be hospitalized,

In all cases, it is necessary to strive for the maximum removal of the pain syndrome. Naturally, the relief of pain is carried out taking into account its pathogenesis and should be only part of the complex therapy of a known or suspected underlying disease.

Important Pointers To Consider For A CT Scan In Case Of Suspected Abdominal Injury

Doctors are concerned about the active appointment of an examination using computed tomography (CT) in paediatric traumatology. With this diagnostic method, the child is exposed to x-rays, which in the long term increases the risk of cancer. Therefore, CT should be prescribed in case of emergency. Before going for a CT scan, it is suggested to first know the CT scan cost in Noida.

A group of American scientists from the University of California School of Medicine at Davis conducted a study to determine the feasibility of appointing a CT scan in cases of suspected abdominal injury. Researchers studied data from a little over twelve thousand patients aged 5 to 16 years who were admitted to the hospital with suspected abdominal injury as a result of an accident or for other reasons from 2007 to 2010.

It turned out that 45% of CT patients were prescribed in the emergency department. In 6%, abdominal injuries were recorded, which could be detected using the method of computed tomography. Only 25% of these patients needed emergency surgery, such as surgery or a blood transfusion.

After analysing the data obtained during the study, experts identified seven main signs indicating a small probability of trauma to the abdominal cavity. They believe that a child should not be sent to a CT scan of the abdomen if:

  • On the stomach there are no traces of the seat belt or other visible damage;
  • No evidence of chest injury;
  • The patient does not complain of abdominal pain;
  • No breathing difficulties;
  • No vomiting.

According to researchers, the predictive value of these rules is 99.9%, sensitivity - 97% and specificity - 42.5. In practice, among patients whose condition was assessed taking into account these signs, in one case out of a thousand, acute abdominal trauma was identified, requiring medical intervention.

How accurate is it to get body scans with high-tech CTs for early diagnosis? Is it possible for any health damages to repeat these examinations every year (even almost every six months)? Are these tests a significant benefit in terms of health protection and early diagnosis of diseases? Let's continue to ask: How accurate is it to perform a CT scan for every headache, neck stiffness, pain in the waist, numbness in the leg?

There is a significant increase in unnecessary CT scans. Due to some unimportant images detected in these scans, people are unnecessarily worried and re-subjected to new CT scans. It is also important that the method is expensive. There is a serious economic loss. There are radiologists who say that no country in the world has as many CT devices as in our country (for example, in Istanbul).

'Needs' should be questioned well

Even if different and new CT scanners have been developed in recent years to help expose them to a lower dose of irradiation, those who plan to have these scans (whether doctor or patient does not notice) need to question the “need” well. When used correctly, it is very important to determine who should perform this screening and how often, under what conditions and the CT scan cost in Delhi. Otherwise, our bodies could become radiation dumps.

Computed Tomography: What Is Important To Know?

Computed tomography is a non-invasive x-ray diagnostic method that can serve as the basis or an additional source of information when making the correct diagnosis and prescribing the necessary treatment.

computed-tomography

Is computed tomography safe?

Yes, CT is considered a safe method. X-ray dose is relatively low. There is a small risk in the presence of concomitant pathology of the kidneys, thyroid gland, bronchial asthma, if the use of contrast agents is used. It is good to know the CT scan price in Delhi before undergoing one.

The patient should warn the doctor if he is allergic to drugs, iodine, seafood, if he suffers from diabetes, bronchial asthma and thyroid diseases and about the drugs that he takes.

During pregnancy, the question of conducting a CT scan is decided by the attending physician; a woman must inform about the presence and timing of pregnancy!

Information for patients:

  1. As a rule, computed tomography is performed without preliminary preparation.
  2. With the use of intravenous contrast agent on an empty stomach.
  3. In chronic diseases of the liver and kidneys without exacerbation, moderate fluid intake is recommended 6 hours before the study.
  4. The study time is 15-25 minutes; scanning itself from 4 to 20 seconds.
  5. During the scan, you need a stationary body position on the table and the ability to carry out breath holding commands for 4-20 seconds.
  6. Before the study, clothing with metal hooks, buttons and zippers should be removed; jewellery in the form of chains and earrings.
  7. With the introduction of a contrast medium, the patient may feel a passing wave of heat.

To undergo research in the CT-MRI department, you should have:

The passport- A referral for the best CT scan in Delhi from a doctor, which indicates:

  1. Name
  2. No. of medical history or outpatient card
  3. The diagnosis
  4. The field of study with the formulation of a specific task (identification, exclusion or confirmation of the presence of changes on the part of the examined organs and systems)
  5. A note on the absence of contraindications for intravenous administration of a contrast medium (if the study is conducted with contrasting). When recording a patient, he is informed of the time of arrival at the department (and not the time of the start of the study)

Relative contraindications to the administration of contrast medium:

  • Pregnancy
  • Allergy to iodine-containing contrast agents
  • Severe hepatic and renal failure
  • Decompensated diabetes mellitus
  • Myeloma
  • Decompensated thyroid disease

Recommendations after computed tomography using a contrast agent:

* It is very rare for patients to have a rash on their skin, etc. - side effect of injection of iodine solution. Therefore, the outpatient should be under the supervision of a doctor in the CT-MRI unit for 2 hours, so that in case of a skin reaction he can receive timely medical help.

* If you have been given a contrast drug intravenously, it is recommended that you drink clean water within the amount allowed by your doctor for a day (1-3 l) in order to speed up the removal of the contrast drug from the body.

Spinal Tumour And Its Treatment – MRI Needed

Tumours originating from the spine bones are usually caused by tumours that develop in other organs that metastasize to the spine. Tumours originating from the direct spine bones are rare. It is more common in the back and waist bones.

Spinal cord tumours can also develop directly from the spinal cord itself or from metastasis of tumours in other organs. Tumours originating from the spinal cord itself may develop from the membrane surrounding the spinal cord, nerves exiting the spinal cord, or directly through the spinal cord.

SYMPTOMS IN SPINE TUMOURS?

The most common symptom is pain. Pain in the region where the bone is held by the tumour, for example in the lower back, in the lower back, and in the back, in the back. Pain usually occurs at rest. If the tumour reaches large dimensions and begins to pressure the spinal cord and the nerves coming out of the spinal cord, pain occurs in one or both legs, numbness or weakness, and if the neck bones, pain in the arms, numbness and weakness are seen.

SYMPTOMS IN SPINAL TUMOURS?

Signs and symptoms of spinal cord tumours vary according to tumour location and tumour size. Symptoms include numbness and numbness in the arms or legs, difficulty walking, loss of sensation of pain or heat, incontinence of urine or large ablutions, paralysis of the arms or legs.

DIAGNOSIS OF SPINE AND SPINAL TUMOURS?

First, a detailed physical examination is performed. Drug (contrast) magnetic resonance imaging (MRI) is the gold standard. In addition to MRI, computed tomography (CT), bone scintigraphy and PET-CT are also used.

TREATMENT OF SPINE AND SPINAL TUMOURS?

The treatment is usually surgical. Surgically removed tumour tissue is sent to pathology to determine whether it is benign or malignant. If benign tumours can be completely removed surgically, there is little chance of recurrence and no additional treatment such as chemotherapy or radiotherapy is necessary. If the tumour is malignant, additional treatment is usually required as there is a possibility of recurrence after surgery.

Treatment

Tumours of the spinal cord can develop inside the parenchyma of the spinal cord by destroying the tissue directly or out of the medullary parenchyma by often compressing the marrow or the nerve roots. Symptoms may include back pain and progressive neurological deficit related to the medullary or radicular involvement. The diagnosis is based on MRI. Treatment may include corticosteroids, surgical excision and radiotherapy.

Surgical excision and radiotherapy

If patients with neurological deficits due to compression of the spinal cord, corticosteroids immediately to reduce spinal edema and preserve its function. Tumours compressing the spinal cord are treated as soon as possible because deficits can quickly become irreversible.

Some well-localized primary tumours of the spinal cord can often be removed surgically. Neurological symptoms are met by almost half of these patients. If the tumourscannot be operated on, radiotherapy is used, with or without surgical decompression. Extradural compressive metastatic tumours are usually excised surgically from the vertebral body and then treated by radiotherapy. Non-compressive metastatic extradural tumours may be treated with radiotherapy alone, but may require excision if radiotherapy is ineffective.

Scanner, MRI, Radio: Which Exam For Which Indication?

Depending on the medical indication, the specificities of the area to be studied, or the profile of the patient, the doctor has a wide choice of medical imaging techniques.

X-ray

Standard radiography uses X-rays that pass through the human body, being more or less absorbed by the tissues according to their density. It allows to obtain two-dimensional images of "full" structures. This technique is, therefore, well suited to the observation of bones and joints. Orthopedics, rheumatology, or orthodontics, use radiography to study trauma (fractures, etc.), skeletal deformities, or the implantation of teeth.

It is also possible to visualize certain organs or hollow parts, usually invisible to X-rays, by "filling" them with an opaque contrast product: this is the contrast radiography.

CT or computed tomography

The scanner, which also uses X-rays, explores the body in volume and thus makes it possible to establish 3D images of organs or tissues scanned: bone, muscles, vessels, or brain. The images obtained are "sectional" images.

The scanner makes it possible to visualize a change of volume or a structural anomaly (tumor, embolism, aneurysm, etc.). It will reveal a narrowing of the coronary arteries in case of chest pain or myocardial infarction. It can also be used in surgery to inform doctors about areas where the intervention is planned, as well as oncology, to control the response to chemotherapy or guide biopsies.

Magnetic resonance imaging (MRI)

The MRI allows to visualize the anatomical structure of the body volume. Anatomic MRI is distinguished from functional MRI.

Anatomical MRI is based on the magnetization of hydrogen atoms present wherever there is water and fat. It is, therefore, particularly adapted to the observation of "soft tissues," such as the brain, the spinal cord, the muscles, the tendons, or the viscera (liver, spleen, and kidney).

Functional MRI is based on the measurement of the deoxy-hemoglobin of red blood cells (the hemoglobin devoid of oxygen leaving the organs). It thus makes it possible to follow the influx of oxygenated blood in the organs, and thus it is very used in the cerebrovascular accidents, but also, in neurology, to make the diagnosis of Alzheimer's disease or multiple sclerosisby visiting MRI test labs in Delhi.

Ultrasound

An ultrasound probe emits ultrasound, sound waves imperceptible to the ear, in the direction of a solid object. They bounce off the object and then return to the starting point. The system allows to explore the heart, the viscera (liver, spleen, pancreas, bladder, bladder, kidneys), and the genital tract (ovaries, uterus, prostate). On the other hand, the digestive tract, the lungs, and the bones are not acceptable.

Doppler ultrasound allows the vascular system to be explored with a thinner probe that can be introduced into the vessel lumen. It is indicated for exploratory examinations in diseases of the veins and arteries. It is important to first know Doppler ultrasound cost.

Finally, ultrasounds of pregnancy, which do not present a danger for the foetus, allow its morphology and its environment: amniotic fluid, placenta, cord.

Chest CT Scan: The Best Way To Detect Lung Cancer

Lung cancer treatment is a process planned according to the patient's condition, type and stage of cancer. The treatment plan also takes into account factors such as the patient's general health and age.

If lung cancer is diagnosed at an early stage, surgical treatment is applied first and the recovery rate is very high. However, if the patient is not eligible for surgery, radiotherapy and / or chemotherapy may be recommended to destroy cancerous cells. Promising results can be obtained from targeted drug therapies in advanced stages of the disease. Deciding which treatment method to use will be increased by a group of specialists.

Lung cancer ranks first among cancer deaths worldwide. Despite the most advanced treatment methods, 86% of the patients die within five years. In the early stage, the probability of five-year survival is around 70%. For this reason, the world of science is making serious efforts to catch lung cancer in the very early stages period when it does not cause any complaint and the person does not need to consult a doctor.

Diagnosis

Tests that examine the lungs are used to detect (find), diagnose and stage non-small cell lung cancer. Tests and procedures to detect, diagnose and stage non-small cell lung cancer are often performed simultaneously. Some of the following tests and procedures can be used:

  • Physical examination and history: A body exam to check the common signs of health including control sings such as lumps, nodes or anything unusual. The doctor will also check the patient’s habits like smoking, work stress, illness and previous treatments or medicine if taken.
  • Laboratory tests- medical procedures that help test blood, urine, tissue or other substances from the body. These tests help in the diagnosis of diseases and further planning and controlling the treatment to monitor the disease over time.
  • Chest X-ray: An x-ray of the organs or bones located inside the chest. These energy beams help creating an image of the areas inside the body.
  • Chest CT scan cost in Delhi: A procedure that helps creating a series of detailed images of different areas within the body such as abdomen, chest. It is taken from different angles.

Who should have a CT scan?

Any patient over 40 years of age and who has smoked significantly (10 cigarettes or more, for 40 years, 20 or more cigarettes a day for 20 years or 40 or more cigarettes a day for 10 years) or smoked less, but with factors of risk of lung cancer: family history of lung cancer, residence for more than one year in the polluted region, occupational or environmental exposure to asbestos or arsenic or personal history of fibrosis and pulmonary emphysema.

Conclusion

Screening for lung cancer is a complex subject. Despite the encouraging results of the NLST study, many uncertainties remain. For this reason, lung cancer screening should not be promoted publicly outside of study protocols. Patients seeking individual screening should be informed in detail of the benefits and risks of screening, and sent at their own expense to multidisciplinary teams experienced in the diagnosis and treatment of lung cancer, who have established standardized procedures to ensure adequate screening. Coordinated and optimal care throughout the screening process.

Despite recommendations published by some expert groups, chest CT scans are still partially experimental and are not currently validated at the population level. It is important to know chest CT scan cost in Delhi before having one.

Tests To Detect Oesophageal Cancer

Usually, oesophageal cancers are discovered when a person has signs or symptoms. If oesophageal cancer is suspected, studies and tests will be necessary to confirm the diagnosis. If cancer is discovered, additional tests will be performed to help determine the extent of cancer.

Medical history and physical exam

If you have symptoms of oesophageal cancer, the doctor will ask questions about your medical history to analyze possible risk factors and learn more about the symptoms.

Your doctor will also do a test to detect possible signs of oesophageal cancer and other medical problems. The doctor will probably pay special attention to your neck and chest areas.

If the test results are abnormal, your doctor will probably order tests to help find the problem. You may also be asked to contact a gastroenterologist (a doctor who specializes in diseases of the digestive system) for further tests and treatment.

Imaging studies to find oesophageal cancer

The imaging using sound waves, X-rays, magnetic fields, or radioactive imaging inside the body substances. Imaging studies can be done for many reasons, such as:

  • Help find a suspicious area that could be cancer
  • Know if cancer has spread, and if so, how far
  • Help determine if the treatment is effective
  • Detect possible signs of cancer returning after treatment

Study with barium intake

In this test, the patient swallows a thick, limestone fluid called barium that covers the walls of the esophagus. When x-rays are taken, barium delineates the esophagus. This test can be done alone or as part of a series of x-rays that include the stomach and part of the intestine, called x-rays of the upper gastrointestinal tract. A barium intake test can show any abnormal area on the normally uniform surface of the inner lining of the esophagus, but cannot be used to determine how far cancer has spread outside the esophagus.

CT scan

A CT (computed tomography, CT) uses x - rays to produce detailed cross-sectionall images of the body. This study can help determine if oesophageal cancer has spread to nearby organs and lymph nodes (bean-shaped groups of immune system cells where cancers often spread first) or to distant parts of the body. Before conducting the study, you may be asked to drink approximately 1 to 2 pints (between half and one liter) of a liquid called oral contrast. This helps to delineate the esophagus and intestines. If you are having trouble swallowing, you should inform your doctor before the CT. Before having a CT scan, it is essential to know CT scan cost in south Delhi.

Magnetic resonance imaging

Like computed tomography (CT), the MRI (magnetic resonance imaging, MRI) provides detailed images of soft tissues. However, MRIs use powerful radio waves and magnets instead of X-rays. To better show the details, a contrast material, called gadolinium, may be injected into a vein before the study is done. MRI can be used to see abnormal areas in the brain and spinal cord that may be due to the spread of cancer.

Positron emission tomography

Generally, the positron emission tomography (positron emission tomography, PET) uses a form of radioactive sugar (known as fluorodeoxyglucose or FDG) is injected into the blood. Normal cells use different amounts of sugar, depending on how fast they are growing. Cancer cells, which grow rapidly, are more likely to absorb larger amounts of radioactive sugar than normal cells. These areas of radioactivity can be seen on a PET CT scan using a special camera.
