Computed Tomography: The Most Effective Methods Of Modern Diagnostics

CT is actually a universal method of diagnosis, which allows the doctor to see the truest picture of the body. The discovery of X-rays has made a real revolution in the diagnosis of diseases. Doctors were finally able to see images of internal organs and bones without surgery. But this method of diagnosis is now obsolete, in addition, it has a number of disadvantages.

Often on an X-ray, images of some internal organs are superimposed on images of others. As a result, only an experienced radiologist can correctly diagnose, and often this is beyond the power of even medical luminaries.

In addition, due to the peculiarities of the examination, the radiograph does not show tumors - such as polyps, hernias or inflammation. These shortcomings of X-rays have prompted scientists to develop new types of diagnostics, among which a special place is occupied by CT (computed tomography) and MRI.

You can have a CT scan in CT scan center in Noida by making an appointment with the consulted doctor.

Computed tomography (CT) is an X-ray examination. But if at a usual X-ray rays pass through a body and are focused on a film or a plate, giving the two-dimensional image at performance of CT the image turns out volume. It depends on the device of the CT machine: the source of X-rays is a ring-shaped contour, inside which is a special couch (table) for the patient.

So, a series of x-rays of organs obtained from different points and at different angles. With the help of a computer, all these images are processed and eventually a three-dimensional image of the organ is modeled.

It is important that the doctor is able to see the "slices" of the body: depending on the settings of the device, the thickness of the cut can be up to 1 mm. This increases the accuracy of the diagnosis.

CT is most often prescribed in the case of:

  • Damage to the bones of the jaw and teeth;
  • Joint damage;
  • Diagnosis of injuries to clearly see visible bleeding;
  • Diseases of the spine, in particular after the detection of hernias, osteoporosis, scoliosis, etc.
  • Detection of brain tumors;
  • Examination of the thoracic cavity (detection of tuberculosis, pneumonia and other diseases);
  • Examination of the thyroid and parathyroid glands;
  • Examination of hollow organs (stomach, intestines);
  • Diagnostics of vascular condition: varicose veins, atherosclerosis, etch
  • Examination of the genitourinary system.

The computed tomography shows tumors, stones, damaged cysts. Therefore, CT is actually a universal method of diagnosis, which allows the doctor to see the truest picture of the body. When diagnosing blood vessels and hollow organs, a contrast agent that does not harm the body is used to increase the accuracy of CT.

Most often, CT scans are prescribed for injuries, especially complex (for example, fractures of the shoulder joint or wrist, where many small bones), to detect bleeding, lung examination, gastric ulcer, kidney disease and other internal organs. To know about lowest cost CT scan in Delhi, contact CT scan centers.

CT scans are not be performed during pregnancy, as X-rays can harm the baby's body. If a woman is breastfeeding, doctors recommend taking a 24-hour break from breastfeeding after the procedure. As for children, CT can be prescribed only if other diagnostic methods have not shown signs of pathology.

CT Scans to Detect Lung Cancer in Smokers

A low-dose helical computed tomography (CT scan center in Noida) scan is a type of medical test. It is used to detect early signs of lung cancer. If the test detects cancer, treatment can start early.

However, the test is not beneficial for people who smoke little or those who quit smoking more than 15 years ago and is generally not recommended for people under 55 or over 80 years of age. Even people who smoke a lot receive only a small benefit from the test, so you should think twice before taking the test.

Who should consider an analysis for detection?

The CT scan cost in Delhi for lung cancer is usually reserved for people who have the highest risk of developing this cancer, such as the following:

·        Older adults who smoke or were smokers. The analysis for the detection of lung cancer, generally, is offered to people of 55 years or more who smoke or were smokers.

·        People who have smoked a lot for many years. You can consider an analysis to detect lung cancer if you have a history of smoking 1 packet per year for 30 years or more. The pack years are calculated by multiplying the number of packets of cigarettes you smoked per day and the number of years you smoked.

·        People who once smoked a lot but stopped smoking. If you smoked a lot for a long time but have quit smoking, you can consider an analysis for the detection of lung cancer.

·        People with good health in general. If you have serious health problems, you are less likely to benefit from the screening test for lung cancer and are more likely to experience complications in follow-up testing. For this reason, the screening for lung cancer is offered to people who are in good general health.

·        In general, screening is not recommended for those who have poor lung function or other serious conditions that could make surgery difficult. This could include people who need continuous oxygen administration, who have suffered thinning without apparent cause in the past year, who have recently shed blood when coughing or who have undergone chest computed tomography screening in the past year.

·        People with a history of lung cancer. If you have been treated for lung cancer for more than five years, you may consider having an analysis for lung cancer screening.

·        People who have other risk factors for lung cancer can be those who have chronic obstructive pulmonary disease, those with a family history of lung cancer and those who are exposed to asbestos at work.

How long the analysis for detection should be continued?

Not all medical groups agree on how old you can consider stopping the test for lung cancer. In general, continue to perform the annual analysis for the detection of lung cancer until the time when you do not benefit from it, as when you manifest other serious conditions that may leave you too weak to undergo cancer treatment.

PET CT Scan for Breast Scanning

For many years now, oncology of mammary glands has been leading in the general statistics of cancers. And the number of cases of breast cancer increases. Therefore, early diagnosis of breast cancer is so important, which allows you to begin treatment without delay and thereby increase the chances of a full recovery.

In modern medicine, methods are used to diagnose breast cancer: biopsy and histology, MRI, mammography, scintigraphy, ultrasound, and PET-CT. The latter approach is the most effective method. With a   PET CT scan, it is possible to see the tumor at the molecular level as part of the diagnosis.

PET-CT Diagnosis in Breast Cancer

PET-CT is a positron emission tomography with the connection of the possibilities of computed tomography. The advantages of PET-CT diagnosis in breast cancer in front of MRI (magnetic resonance imaging) and CT are apparent: this technique not only fixes structural changes in tissues but also provides information about the dynamics and quality of the changes that occur.

Today, in most modern cancer centers, this highly sensitive method is used. But in the PET-CT examination, the scanner is not essential in itself, but the presence of radioactive contrast substances, which are intravenously administered to the patient before the start of the study and accumulate in the cancer cells of a particular disease.

CT scan center in Noida specialists have long experience and skills in the application of the PET-CT method and develop new contrast agents for research, including breast cancer.

During the Whole Cycle of Breast Cancer Treatment, Clinic Specialists use PET-CT Studies at Various Stages:

-        At the scene of diagnosis, PET-CT with FES, and FDG allow determining the spread of cancer beyond the breast.

-        At the scene of treatment, PET-CT can track the effectiveness of the therapy.

-        In some cases, PET-CT with a particular isotope is used in the planning of radiation therapy.

-      When metastasizing breast cancer into bone tissue, clinic specialists conduct PET-CT with the isotope Naf, which is more sensitive than usual scintigraphy.

-        With hormonal types of breast cancer in the clinic, a PET-CT scan with the FES isotope is conducted.

According to the consequences of the study, specialists write an opinion for oncologists. Description of pictures PET-CT requires specialized knowledge and experience in diagnosis. The specialist should be able to distinguish between the accumulations of contrast in cancer cells from other changes.

PET CT scan in Delhi forbreast cancer makes it possible for specialists to see the spread of the disease in soft tissues, bone tissue, and distant organs. This allows specialists to make surgical intervention high-precision, and medical and radiation treatment - the most effective.

The experience of specialized clinics says that conducting PET-CT diagnostics in breast cancer often leads to a change in the treatment regimen since it reveals features that cannot be seen with other methods of investigation. So, with the use of this modern method, the prescribed treatment - surgery, preparations for chemo-immunotherapy, radiotherapy or a combination of several ways, acts more specifically, causing minimal damage to the general condition of the body. Correctly selected treatment improves prognosis and reduces the risk of complications from ongoing therapy and relapses.
