Magnetic Resonance Imaging (MRI) And Medical Considerations

If you or your child need an MRI, that is, an MRI, you should know that the procedure is safe.

Many people will never need to have an MRI scan, and if you have a cochlear implant, there may be other diagnostic tools available to use. In fact, 85% of radiology professionals agree that they have an alternative diagnostic tool for those who cannot undergo magnetic resonance due to having a device or a magnet implant.

Magnet removal for better head and neck MRI studies

If you must undergo an MRI scan of the head, the presence of the cochlear implant magnet will distort the MRI scan image of any power. Regardless of what brand of implant you have, for the MRI scans of the brain in general you need to remove the magnet.

You can remove and replace the implant magnet with a medical procedure if necessary. In the unlikely event that you or your child need repeated MRIs, there is an option without a magnet.

Neuroimaging: Role of MRI

Magnetic resonance imaging can produce not only morphological images but also functional ones and its range of indications is extended day by day, invading the terrain of other modalities (CT, angiography, PET, ultrasound, etc.). There are currently two techniques in MRI that are leading the research, functional magnetic resonance imaging (MRI).

Determining the merits of a given medical imaging test poses a complex and multidimensional problem. In fact, the merits of an examination may depend on the patient's age, sex, size and physical limits. It may also depend on the disorder and symptoms under review

Making good decisions about medical imaging is further complicated by the fact that imaging techniques are evolving rapidly and that some clinical cases and exams are difficult. Furthermore, understanding the rationale for prescribing practices for diagnostic imaging exams is further complicated by an increasing trend in the number of specialists (e.g. cardiologists, obstetricians, rheumatologists, neurologists and oncologists) who order diagnostic imaging tests and interpret images and, in some cases, run imaging laboratories.

The use of advanced diagnostic imaging is likely to continue to increase over the next decade due to the above factors. Other factors may also contribute to the continued growth in the use of advanced diagnostic imaging. For example, the increased use of CT may be due in part to the interest it has had as a screening tool, particularly for lung cancer in smokers and former smokers, heart disease and colon cancer.

Similarly, it is likely that PET/CT will play an increasingly important role, as new radioactive indicators will broaden the range of clinical disorders that it can diagnose. It remains to be seen whether this possible increase in use will result in an increase in the frequency of inappropriate use.

What Does The 3Tesla Resonance Will Reveal The Multiple Sclerosis?

It has been announced as an important advance in the diagnosis of multiple sclerosis, an autoimmune disease of the central nervous system that affects 75,000 Italians and 2.5 million people worldwide.

This is the demonstration that it is possible to identify the brain lesions typical of multiple sclerosis (MS), distinguishing them from similar injuries but due to other pathologies, using a 3 Tesla (3T) magnetic resonance instead of 7 Tesla (7T), more powerful equipment that allows this discrimination in an easy way but that is still mainly used only for research purposes.

WHAT IS MULTIPLE SCLEROSIS

Multiple sclerosis (MS) is a disease related to the central nervous system in which the immune system affects the myelin sheath that coats the nerve fibers in the brain, spinal cord, and optic nerves. As this process progresses, which also causes the appearance of scars (sclerosis), they gradually lose the ability to transmit the electrical signal to other nerves. It can occur in people of any age and condition; it has mainly a chronic course in which the disease progresses and can cause serious disability.

WHY THE NEUROIMAGING IS SO IMPORTANT

High cost of 3t brain MRI has powerful scanners that resonate the protons of our body, mostly contained in the water of which we are made, and transform the signal they emit into extremely precise images of anatomical structures.

In the case of the brain, the detail is very high up to being able to identify even very small brain structures, such as venules. Pathological changes appear as alterations of this signal. Unfortunately, however, many lesions of extremely different pathologies resemble each other from the point of view of the signal, but understanding exactly where they are located nevertheless greatly helps the diagnosis. For example, MS lesions are perivenular.

And so, as far as the diagnosis of this pathology is clinical, high-field resonance is often necessary, so much so that it is included among the examinations required by diagnostic criteria recognized by the scientific community.

Being able to distinguish in this way, brain lesions from MS from other brain lesions with MRI is therefore fundamental for the diagnosis in cases where some lesion appears, but its nature is not clear.

And making the diagnosis immediately and very quickly is very important because we must try to stop the disease as soon as possible. But a resonance of a certain sensibility counts above all in the progression controls of the illness, when the «lesion load» is evaluated; when new lesions appear from one control to the other, seeing them or not seeing them, or exchanging a new vascular-type lesion with an MS lesion can change the therapy. MRI images are equally important in therapeutic monitoring, ie, in assessing the effects of therapies.

Modern high and very high field imaging machines allow us to obtain highly detailed high-resolution images and are used for the study of numerous neurodegenerative and inflammatory diseases. It is in this part of patients that the new discovery is inserted, moving in the clinical field a technique developed on the very high field of Cost of 3t MRI in Delhi.

PET CT Scan For Cancer, Heart Problems, Brain Disorders, Nervous System Diagnosis

pet scan for cancer

What is a PET Scan?

PET is a positron emission tomography that makes your doctor check your body for various diseases. In this type of a scan special dyes are used and these dyes have radioactive tracers. After the tracers are injected into a vein of your arm, your organs and tissues start absorbing the tracer. Your body is put under a PET scanner and your doctor is able to find out whether your organs and tissues are working appropriately or not. The PET CT scan helps your doctor to find the blood flow, usage of the oxygen and usage of the sugar by your body, glucose metabolism and many more diseases.

This procedure is an outpatient procedure which implies that you are allowed to go back home after the completion of the procedure.

Why is the PET Scan done?

The PET scan is done to diagnose whether you are suffering from the following diseases or not-

Though other imaging tests like the CT scan and the MRI are also beneficial yet PET scans are able to diagnose the problems persisting at the cellular level. This enables the doctor to very clearly view the diseases called as the complex systemic diseases like

  • Brain tumours
  • Seizures
  • Memory disorders
  • Coronary artery disease
  • Lung Cancer Lymph Nodes
  • PET scan for diabetics

When PET is used for diagnosing the cancer, it helps your doctor to view very clearly the metabolization of the cancer and to know the areas to which the cancer has spread. The response of the tumour to the chemotherapy is also shown using the PET.

What is the procedure of the PET Scan?

During the PET scan procedure, you’ll either be given a gas to inhale or else a solution to drink. You might be given tracers via a vein in your arm. For absorbing the tracers, your body would need some time, therefore, you’ll be asked to wait for about an hour tentatively before the beginning of the scan.

Now you’ll be made to lie on a narrow table and this table would be attached to the PET machine. The table will be made to glide into the machine. This would be a slow procedure.

You’ll be asked not to move at all during the scan. You’ll also be asked not to breathe for some time. While the test would be on, you’ll be made to hear buzzing and clicking noises.

When all the important images would be recorded, you’ll be made to slide out of the machine. Your test would have completed.

After the test gets completed, you’ll be asked to carry on your normal day. You might be given certain instructions by the doctor. You’ll be asked to drink ample fluids for letting you flush the tracers out of your body’s system. Mostly, it takes about two days to let all the tracers leave your body.

When will you get your PET CT Scan results?

PET scan results would be available within 24-48 hours. A trained specialist will be asked to interpret the images of the PET. This information will be shared will your doctor. Your doctor with you will go through your results at your follow up appointment.

How should you prepare yourself for the PET scan?

Complete instructions will be given to you by your doctor for the PET scan preparation (rules). You should reveal your prescriptions and the medicines being taken by you to your doctor. You will not be allowed to eat anything for more than eight hours before the procedure takes place though you’ll be allowed to drink water.

In case if you are pregnant, you should tell your doctor because the test could be unsafe for your baby. You’ll be given special instructions for your test in case if you are Diabetic because fasting may impact your sugar levels of the blood.

Hospital will provide you with a gown to wear and will ask you to remove your jewellery as metal can be an interference in the procedure.

How much would the PET Scan Cost?

You can get the PET scan of your chest, brain or the whole body done at various diagnostic centres associated with 3HCare. Cost of PET CT scan can differ at different labs. To get a transparent and competitive pricing for your scan, logon to 3H Care portal and book your test.
