How To Determine The Cause Of "Knee Pain"?

One of the most common complaints after outdoor activities is a pain in the knee joint. Its cause can be both sharp traumatic effects and prolonged static loads. If you are concerned about “knee pain”, then you need to consult a traumatologist, because in some cases joint pain can be a harbinger of serious pathology.

Diagnosis of the causes of "knee pain"

In the vast majority of cases, the damage is complex, and without visualization of damaged structures to identify problem areas can be problematic. For this, an MRI study is performed by MRI scan centre in New Delhi to study the anatomical structures of the joint and identify the cause of the pain.

In the knee joint are most often damaged:

  • Menisci (red markers)
  • Bags of the joint in the form of inflammation.
  • Ligaments:
  • Cruciform- front and back
  • Collateral
  • Own patellar ligament

When does it make sense to examine an MRI of the knee?

With each step, the knee joints experience a three-dimensional load of the weight of the whole organism. For a short period, the knee can withstand much more. Like no other joint, the knee provides mobility. Cartilage and meniscus absorb a heavy load, and the ligaments further stabilize the knee.

Often, problems with the knee joint occur in children and adolescents in connection with growth, since the individual elements of the knee joint must constantly adapt to each other.

The knee joint is already inherently subjected to a constant load, and the additional load (for example, during sports) causes damage to it. Excessive rotation often causes ligament rupture, especially the cruciate ligament. An overload can also lead to the rupture of the meniscus. These two diagnoses cannot be made by X-ray. This requires an MRI scan.

In addition, the knee joint refers to those joints that are the most susceptible to wear (arthrosis). An MRI scanner shows how worn the cartilage is. Determining the degree of wear is very important in developing a treatment plan.

What is this survey?

Using a strong magnetic field, the internal structures of the knee are visualized in the framework of magnetic resonance imaging. This allows MRI scan centres in east Delhi to make an accurate diagnosis.

If the artificial knee cannot be avoided, then MRI images are an important part in terms of preparing the patient for surgery. It is necessary to clearly determine the type and position of the artificial joint.

As part of the examination (examination lasts up to 20 minutes), you lie on a movable couch, which is sent to the tunnel. It is open front and back. Using a strong magnetic field, layered images of the knee are created to consider the smallest changes. Such changes cannot be detected using x-rays, and the examination is painless and takes place for the patient in a gentle manner.

If necessary, a contrast agent is introduced in order to better consider the individual parts of the knee joint and possible damage. The used contrast medium does not contain iodine and only in rare cases, causes side effects.

Diagnostic Imaging Of The Chest – Lung Scan

The diagnostic imaging of the chest includes radiography, computed tomography (CT), magnetic resonance imaging (MRI), scintigraphy, ultrasound, and positron emission tomography (PET). Radiography is almost always performed. Other imaging tests are carried out as necessary to obtain specific information for the purpose of formulating the diagnosis.

The chest X-ray

It is performed routinely from the back to the front. In general, an image of the lateral section is also acquired. Chest X-rays provide a good definition of the profile of the heart and large blood vessels and can usually reveal a serious disease of the lungs, pleural cavities, or rib cage, including the ribs. For example, chest radiographs may show pneumonia, some lung cancers, chronic obstructive pulmonary disease, lung collapse (atelectasis), and the passage of air (pneumothorax) or fluid (pleural effusion) in the pleural cavity. Although thoracic radiographs rarely provide sufficient information to determine the exact cause of these abnormalities.

A computed tomography (CT) of the chest provides more detail than a simple radiograph. With the CT, a series of radiological images is analyzed with a computer, which, subsequently, provides multiple projections on different planes, such as longitudinal and transverse sections. Before having a CT scan it is good to know CT scan cost in Delhi NCR. During CT, a visible X-ray substance (called a radiopaque contrast agent) can be injected into the bloodstream or administered orally to establish the nature of certain abnormalities in the chest. High-resolution CT and spiral CT are more specialized CT procedures. High-resolution CT can reveal further details in relation to lung diseases. Spiral CT can produce three-dimensional images.

It includes the injection of a radiopaque contrast medium into a vein in the arm to create images of blood vessels, along with the artery that carries blood from the heart to the lungs (pulmonary artery). Currently, angiography is used instead of scintigraphy to diagnose the presence of blood clots in the pulmonary artery (pulmonary embolism).

Even the magnetic resonance imaging (MRI) provides very detailed images, which are especially useful in the case of vascular changes suspect in the chest, such as an aortic aneurysm. However, the MRI takes longer and has higher costs than the TC. Furthermore, the MRI resolution is lower than that of CT for the diagnosis of abnormalities in the lungs, and therefore this examination is not frequently used in the field of diagnostic imaging. The cost of CT scan in Delhi vary according to the place it is going to be held. Unlike CT, MRI does not use radiation.

The lung scan may be useful to detect the presence of blood clots in the lungs (pulmonary emboli); however, in the diagnostic process of this disease, it has been largely replaced by ' CT angiography. Scintigraphy can also be used during the preoperative evaluation of patients with lung cancer. Pulmonary scintigraphy uses modest amounts of short-lived radioactive material to define the flow of air and blood through the lungs. Usually, the test is performed in two phases.

In the first phase (perfusional lung scan), a radioactive substance is injected into a vein, and a scanner reproduces an image of the mode of distribution through the pulmonary vessels. If the perfusion ultrasonography is altered, a second phase (pulmonary ventilation ultrasound) is required; the patient inhales a radioactive gas, and the apparatus produces an image of the distributive pattern through the lungs.

Chances Of Men Getting Affected By UTI

While women are far more likely to experience a urinary tract infection (UTI), men are not immune to this problem. In fact, an estimated three percent of men get a UTI every year.

Most bacteria that enter your urinary tract are washed out when you urinate. If bacteria stay in your urinary tract, you may get a UTI – an infection of the bladder and urethra (the lower urinary tract) and sometimes the kidney and ureters (the upper urinary tract). UTIs are less common in men. This is because compared to a man; the urethra (the tube that drains urine from the bladder) is shorter in a woman and closer to the anus, and therefore more susceptible to bacterial infection. While rare in men under 50, UTIs become more likely as men age. The risk of developing a UTI increases due to problems such as an enlarged prostate that prevents the bladder from emptying properly; kidney stones or other bladder or kidney problems that prevent proper urination; or a weak immune system. In some cases, a male UTI can occur for no apparent reason.

What are the symptoms of a male UTI?

When a man does get a UTI, symptoms is not much different than those a woman would experience. Typical symptoms of UTI in men include:

  • Constant urge to urinate
  • Pain or burning when urinating
  • Pain or pressure in the lower abdomen
  • Cloudy, bloody or foul-smelling urine
  • Leaking urine
  • Fever

The process by which male UTI is treated

Though many UTIs are minor and resolve within a short time, it is appropriate to seek medical attention if you experience any of the above symptoms. Men and women receive the same treatment for a UTI, typically antibiotics to kill bacteria and stop symptoms. A higher percentage of men reports improvement within a few days of starting treatment.

Get UTI Diagnosis & Treatment

If you have the symptoms discussed previously, simply walk into for immediate treatment recommendations with by setting up a date for appointment. The board-certified nurse practitioners and physician assistants start the process to diagnose a urinary tract infection using urinalysis, which detects bacteria and blood in the urine. The diagnostic labs in Delhi are mostly open seven days a week which makes it very easy to seek consultation. This way, you can get an informed picture of what has been gripping on you. Many people may relate this to something which can create a social awkwardness. But the fact of the matter is that men too should not be shamed when it comes to discussing a medical condition like this. Moreover, UTI has also been linked to sexually transmitted disease or STD. Therefore, one should always make sure to not have unprotected sex as the chances of UTI is said to be the most for these negligence. In addition, it is also advised you opt for bland foods to ease the burning sensation whilst the medicines are being taken.

MRI For Children: Diagnosis Without Fear

Magnetic resonance imaging has long established itself as a reliable diagnostic method that can identify pathology at an early stage of development. But despite the assurances of the doctors that the procedure is completely safe, many are still distrustful of this type of diagnosis. And especially when it comes to examining a child.

The first and main question: is an MRI scan safe for children?

The tomography itself does not carry any danger to humans. It works without the formation of any harmful radiation, unlike x-rays or computed tomography. Diagnosis is based on the influence of a powerful magnetic field and radio frequency waves on a specific area of ​​the body. I emphasize: it is harmless to both an adult and a child. And we get high-precision images in any plane, visualizing anatomical sections. These images allow you to most accurately diagnose and determine the treatment strategy.

At what age is MRI test in east Delhi prescribed for children? And what can be identified using such a diagnosis?

- Numerous studies have proven the complete harmlessness of MRI, suggest that the procedure can be prescribed even to new-borns. Moreover, with the help of a tomography, we can even conduct an examination of the foetus, which is still in the womb, to exclude developmental abnormalities. But this is done only according to the testimony of doctors and only in the last trimester of pregnancy. For babies up to a year, MRI is prescribed to identify congenital pathologies or if there is a suspicion of developing an infectious disease that can cause complications, including to the central nervous system.

There are situations when new-borns have cerebral haemorrhages or ischemia, when the brain receives insufficient nutrition. It is difficult to do without MRI if it is a suspicion of oncological processes: unfortunately, no adults are safe from them, no children. All these conditions require different treatment, but they have one thing in common: in such cases, an urgent and reliable diagnosis is needed. The sooner we figure out what’s the matter, the sooner we can help the child.

How is the procedure going and are there any differences between MRI for children and adults?

- At first glance, there are no global differences in MRI for an adult and a child. The bottom line is one: a person is located on the table of the tomography, the apparatus is configured depending on the area being studied and the patient’s parameters.

The procedure lasts from 20 minutes to an hour. After processing the results by a computer, the doctor receives a reliable image of certain organs in the form of layered images. Nevertheless, the MR diagnosis of the child has its own nuances. Any childhood age has features that need to be considered.

A newborn, a five-year-old baby, a teenager - they require a different approach to the examination. Firstly, the MRI device is set up in a certain way; the corresponding programs are selected. Secondly, depending on age approaches to preparing a child for the procedure also change. During the examination, the patient is required to be completely still - otherwise, we will not get clear pictures.

And if it is quite possible to explain this to a teenager, then with kids under 5 years old a completely different story. They do not understand what is happening, they can’t lie still, and they are scared of equipment and doctors. To know the MRI scan price in Delhi, you will have to consult the MRI labs. There is only one way out - to have an MRI under anaesthesia.

Magnetic Resonance In Children

Brain resonance is primarily used when a structural brain injury is suspected, that is, a problem that we can "photograph."

As in all the complementary tests, the information it offers is of no value if the context of symptoms and signs of the patient that the neurosurgeon will have obtained during the medical visit and with which he will develop a diagnostic hypothesis is not taken into account.

It is essential in the study of pathologies that occur with alterations in brain structure such as childhood cerebral palsy, malformations, or the consequences of trauma or infection, among others.

It is also used in the study of some types of epilepsy, to ensure that there is no underlying cause. And very rarely before a headache.

For the study of vascular diseases, tumours, neurodegenerative processes, and prior to brain surgery, the MRI images are combined with other special resonance techniques:

  • Spectroscopy:

Provides information on brain metabolism

  • Diffusion: study the microscopic molecular movement
  • Perfusion: allows to see cerebral blood flow
  • Angiography:

Visualize, after contrast injection, arteries, and veins

  • Tractography:

To see the structure of brain fibers

  • Functional MRI:

The image is obtained while the patient performs a task and their brain activity is studied

How is a resonance made?

Unlike other imaging techniques, such as simple radiology or CT, magnetic resonance imaging does not use radiation (X-rays), but rather very strong magnets and radio waves that have no side effects. This makes resonance, along with ultrasound, the safest and safest procedure to obtain body images.

The waves pass through the tissue to be studied, finding different resistance depending on the amount of water it contains. Thus, the device produces a very reliable and accurate map of the studied area much sharper than that obtained by other techniques.

The strong magnetic fields that are created during an MRI force to remove all metal objects from the room. Even smaller objects cause interference by vibrating under the force of the magnet, resulting in blurry images without utility, large objects can fly away, causing accidents. Before having an MRI, one should know the MRI test cost in Noida.

That is why the patient should take off his clothes and put on a hospital gown before laying him on the narrow stretcher that slides inside the resonance tube. To better visualize the images, contrast is sometimes given to the patient through an intravenous line. The most widely used is gadolinium, which is very safe and rarely causes side effects - nausea and local pain - and very rarely allergic reactions. It is contraindicated in patients with severe kidney problems.

The time required to obtain the images is very long, about 30 minutes minimum - depending on the surface to be studied, and the patient must be absolutely still so that they do not get blurred. In addition, the intense noise of the device prevents spontaneous sleep. Children under 6 years of age and children with difficulties to collaborate need to be sedated so that the MRI obtains clear images. Sedation will be done by MRI test labs in Delhi who will be present throughout the examination.

The Magnetic Resonance Imaging And Its Development

Although the lack of vocalization when speaking or partial paralysis can simply be signs of an attack or a migraine, they can also be symptoms of a stroke. Cerebral infarctions are the third leading cause of death in the United States and one of the leading causes of severe disability.

More than 3 million people who have survived a stroke have become unable to work or take care of themselves. For this reason, when a patient enters an emergency room with these symptoms, doctors must make a crucial diagnosis without losing a second. Although the number is still small, there are more and more hospitals that can perform ultrasound MRI of the patient's brain using a technique called functional magnetic resonance.

In just a few minutes, the scanner reveals not only if the patient has suffered a stroke but also which part of the brain is at risk. The urgency of this diagnosis should not be underestimated. As one neurologist once said, "Time is brain. The earlier the diagnosis is made and treatment begin, the greater the part of the brain that can be saved."

This tool for the diagnosis of cerebral infarctions represents the first important clinical application of functional magnetic resonance imaging. Since the early 1990s, functional magnetic resonance imaging has helped neurology researchers learn more about brain functioning, as it allows them to observe the changes that occur in the chemical composition of different areas, as well as changes that occur in the circulation of fluids in a matter of seconds or minutes. Functional magnetic resonance imaging can also be used to better understand the physiology of other organs.

Conventional magnetic resonance imaging by MRI test labs in Delhi which provides detailed images of the anatomical structure, also plays an essential role in observing other parts of the body. It allows to detect symptoms of arterial sclerosis in the heart, as well as herniated discs, broken cartilage and tumors in the spine, bones, and joints. In all these cases, magnetic resonance imaging is performed without the need for painful interventions.

The basic investigations that led to magnetic resonance and functional magnetic resonance began in a series of physics laboratories in the first decades of the 19th century. This article describes the path, often tortuous, that has been traveled during the last 70 years from the work of a series of scientists who simply investigated the nature of matter to current applications that ultimately save many lives.

The images of the human brain obtained by functional magnetic resonance represent the most recent advance in a field that was born just 20 years ago. Currently, scientists use functional magnetic resonance imaging to study the changes that occur in the brain activity of patients who have suffered a stroke and who begin to recover lost skills, with the aim of developing more effective treatments and therapies.

The functional magnetic resonance imaging allows investigating the development of the neural networks of the motor, visual, auditory, and speech systems of a baby when listening to the voice of his mother. MRI done by MRI scan center in New Delhi can also help to understand the subtle abnormalities in the activation of the brain in children with problems of lack of attention due to hyperactivity and memory problems of patients with schizophrenia.

MRI- An Imaging Study To Diagnose The Diseases

Magnetic resonance imaging is a modern method for studying the structure, condition, and function of internal organs. It is based on the measurement of electromagnetic waves emanating from body tissues. These signals are transmitted to a computer, which decodes them and converts them into an image. The obtained data is analyzed and evaluated by a specialist conducting an MRI.

Modern equipment allows obtaining a three-dimensional image of the internal organs so that the study has high information content. MRI helps to identify a large number of diseases that are not so accurately diagnosed using other methods.

MRI has great advantages over invasive and radiographic methods, as it is a safe and comfortable procedure. Due to this, the study is used in the diagnosis of diseases of many organs and systems:

  • Brain;
  • Vessels of the neck and brain;
  • Jaw and temporomandibular joint;
  • Joints;
  • Spinal cord;
  • Spine;
  • Abdominal organs;
  • Pelvic organs;
  • Respiratory system;
  • Endocrine system;
  • Lymphatic system;
  • Reproductive system.

One of the most common areas of magnetic resonance imaging in the diagnosis of diseases of the nervous system. MRI of the brain allows detecting tumors and determining the stage of their development, diagnosing problems with vessels, multiple sclerosis, and other pathologies.

Many patients are interested in - with MRI of the brain, radiation occurs, and is it dangerous? What dose of radiation does the body receive during the research? Is MRI Hazardous to Health?

MRI Radiation Level

Unlike X-rays and computed tomography (CT), patients receive a zero dose of radiation during an MRI scan, since this study is not based on ionizing radiation, but on electromagnetic effects.

The effect of a magnetic resonance imager is comparable to that of a cell phone or microwave. MRI done by MRI test labs in Delhi does not cause irregularities in the structure, condition, and function of tissues and organs, being at the same time a highly accurate diagnostic method.

Therefore, you can be sure that there is no radiation during an MRI scan of the brain.

Magnetic resonance imaging in oncopathology?

Patients with oncologic MRI are prescribed with the use of a contrast agent - to increase the information content of the study: this allows a detailed study of the tumor and its vascular network. Due to the high precision and diagnosis, the most effective treatment is prescribed.

The absence of irradiation provides the possibility of using MRI for cancer patients with confirmed diagnoses of various malignant tumors, which are not recommended for X-ray methods. X-ray and computed tomography due to ionizing radiation harm the tissues of the body: cause changes in DNA and adversely affect the already existing pathological processes. Electromagnetic effects during MRI are safe for both tumors and healthy tissues and organs.

How often can I do magnetic resonance imaging?

In the absence of contraindications, MRI may be prescribed - depending on the disease and the characteristics of its course - as often as necessary to develop an effective treatment plan or to correct it. Since the procedure is safe for the body, it can be carried out with a minimum time interval.

The frequency of an MRI can only be determined by a doctor. If there is an urgent need or in accordance with the developed plan of dynamic observation, the study is carried out several times in one day.

Is It Possible To Do CT And MRI For Children?

Imagine that a doctor prescribes your child to undergo a computed tomography or magnetic resonance imaging. Most likely, you are, first of all, thinking about the possible risks: will this or that research harm the children's organism? How will the child take them?

Is there a danger?

Magnetic resonance imaging (MRI) is an absolutely safe method of research, since it does not use ionizing radiation sources. There is no reason to worry about the hypothetical harm to the child from this type of diagnosis. When conducting computed tomography (CT), X-rays are used, so the concerns of the parents are well founded. But in the medical organizations of the Moscow Department of Health, special pediatric research protocols are used, which allow reducing the radiation dose to the minimum harmless values. Therefore, this procedure does not have any negative impact.

Is it possible to replace a CT scan with a safer MRI?

MRI and CT are two different methods of radiation diagnosis, which are not always interchangeable. They give different information about the state of health, so the question of what kind of research to conduct a child is decided directly by the attending physician or radiologist. The greatest harm to health is caused not by a microdose of X-rays, but by insufficient diagnostics.

Is it necessary to give children anesthesia during CT and MRI?

During CT and especially MRI, it is very important that the child remains stationary throughout the procedure; otherwise, the results will not be accurate or not suitable for analysis. The MRI procedure takes an average of 20-30 minutes, which means that the child will have to lie motionless all this time. As practice shows, children 5-6 years and older do an excellent job with this task. But earlier patients are difficult to maintain immobility.

For children under 3 years old, CT and MRI are performed only in a hospital, under the supervision of specialists. Before the study, the child is given a sedative or mild inhalation anesthesia, after which he wakes up quickly and easily.

CT and MRI with contrast enhancement

To diagnose some diseases, a child may need to have a CT scan or MRI with a so-called contrast - and you should not be afraid of this study. Before the procedure, the doctor will carefully collect anamnesis and find out all about possible contraindications. For greater safety, a study with contrast enhancement in children is carried out only in hospitals.

Where will my child be taken for CT and MRI?

According to the order of the Moscow Department of Health, the routing of children on CT and MRI in hospitals is carried out in accordance with the assignment by the district. That is, depending on the CT scan centre in which you are monitored, you will be assigned a referral to one or another institution.

In most cases, children under 3 years old are sent to inpatient medical organizations for CT and MRI. This is due to the need to introduce anesthesia for the success of the study. Children over 4 years old can undergo an outpatient study.

Why is Magnetic Resonance so Noisy?

In past years, magnetic resonance imaging (MRI diagnostic labs in Delhi) has become one of the most requested tests within a diagnostic imaging service thanks to its great potential to differentiate the different tissues that make up the human body, but why is it so noisy? It is the question that many patients ask themselves at the end of the test.

The Magnetic resonance machine basically consists of a powerful magnet, mostly superconductors, with a transmitter and a radio wave receiver, in addition to all the electronics necessary to coordinate its operation. The magnet creates a powerful magnetic field even more powerful than that of the earth, the transmitter, in turn, emits radio waves that are directed towards the patient, these waves excite the protons of the different tissues and the receiver picks up the signal emitted with which will create the image.

There are four magnets, one main, the largest and most powerful, and the other three smaller ones are the gradients, which are inside a large metal coil called a gradient coil. This coil is composed of copper electromagnets that create a secondary magnetic field in each of the three directions of space and fulfill a fundamental function since they are responsible for spatially locating the RM signal and coding it in order to create the image.

What is so much acoustic noise? To create the magnetic field an electric current has to be applied and when this is applied in the presence of a static magnetic field they produce variable magnetic forces that act on the gradient coil (mechanical vibration) and cause it to expand and contract rapidly in a matter of milliseconds producing movements or vibrations generating noise that is manifested throughout the room, so we can say that the main responsible for the noise generated by the magnetic resonance machine are the gradient coils.

There are other factors that contribute to generate noise such as the modification of acquisition parameters, acoustic noise tends to improve with the reduction of the thickness of cut, the field of vision (FOV), RT (repetition time) and ET (echo time) but this may affect the resulting image.

On the other hand, the acoustic noise characteristics have a spatial dependence depending on the position and the size of the patient; the levels can vary by about 10dB.

Studies conducted including a variety of pulse sequences where several gradients are applied resulted in this type of sequences (3D and GR) being among the strongest with levels ranging from 103-113 dB. Other studies also measured the acoustic noise generated by echo planar (EPI) and FSE (fast spin echo) sequences in 1.5T, noise levels ranging from 114 to 115 dB and in 3T levels in the range of 126 to 131 dB for these noise levels the use of hearing protection is recommended.

When the patient asks about technical issues like this we cannot use a very technical language since the patient would not understand us, we have to find a way to make ourselves understood in order to satisfy their curiosity. A patient informed about the MRI test cost in Noida that is going to be performed tends to collaborate and feel safer.
