It would be important to know that these days Positron emission tomography (PET) has turned out to be an important cancer imaging instrument, both for the diagnosis and staging also for catering prognostic information on the basis of response. PET scans are somewhat fresh forms of medical imaging that began to be used in clinical settings near the decade of 1990s. A diagnostic PET scan is used by experts or physicians to find out the biochemical changes taking place within a patient while a metabolic PET scan is employed to diagnose, stage and also follow-up on the tasks administered.

Moreover since it studies metabolic functions of the patient, PET imaging can also be put to use as an alternative to that of biopsy and even othertypes of exploratory surgeries performed to decide how far a health problem has spread.
Exceptional capability of PET scan
The capability of this PET scan to distinguish between non-cancerous and cancerous tumours is absolutely spectacular.

The purpose of PET
Positron emission tomography has a large range of diagnostic applications but is specifically ordered in case your doctor either suspects cancer or that a cancer could have scattered. It is used regularlyto measure the status of the heart prior to that of bypass surgery. It is mainly in case other imaging tests are irresolute.

PET differs from MRI and CT in a way that it examines the active, living cells and measures how they function. By contrast, CT and MRI get employed to find out any type of damage caused by an illness. In spirit, PET aims at how the body responds to a specific illness, while computed tomography (CT) and magnetic resonance imaging (MRI) find out the harm triggered by one.
Amidst its various kinds of functions, PET can evaluate oxygen intake, blood flow, howthe body make use of glucose (sugar), and speed by which a particular cell duplicates. By classifyingthe abnormalities in cellular metabolism, a PET scan can find out the early start of an ailment much before other imaging tests. Moreover PET can get used to diagnose various types of conditions depend onthe kind of radiotracer used. The most usual tracer, known as fluorodeoxyglucose (FDG), gets employed in ninety percent of PET scans, the procedureof which is generally referred to as FDG-PET.
When it is injected into the bloodstream, FDG is taken up by glucose molecules in cells. It is because the cancer cells multiply quicklyand do not experience programmed cell death the way normal cells do, these shall take up far more FDG in the duration of metabolizing sugar. Similarly FDG can also get used to underline the zones of low metabolic activity activatedby the obstacle of blood flow. And yes, FDG-PET can also perceive the changes in oxygen and glucose levels in the brain consistent with impairment, ailment,and psychiatric ailment.
You should note that the procedure of PET scan is not at all painful. You would not experience any uneasiness or pain. Of course, injection might be given to soothe you but that would not be a big deal for you right? The duration of the scan would depend on the area getting scanned though such scans do take time of 40 to eighty minutes.
Conclusion
Thus, you can look for pet CT scan centres in Mumbai and make sure that you take the appointment as soon as possible.
