A positron emission tomography scan abbreviated as a PET scan is recognized as a state-of-the-art imaging test that supports in nicely revealing how the organs and tissues of your body are functioning. A PET scan makes use of a tracer, essentially a radioactive drug to display the courses of activity. Occasionally, this scan can be used for detecting a disease prior to it being shown up on several other imaging tests.

• In the course of a PET scan, you might be injected, made to swallow, or inhale the tracer based on the type of organ or tissue that needs to be ’studied.
• The tracer usually accumulates in certain body areas which have greater levels of chemical activity that, in turn, frequently correspond to areas being affected by any disease.
• On the images derived from a PET scan, these areas are exhibited as bright, distinct spots.
• A PET scan comes of good use while exposing or assessing a variety of conditions including heart diseases, brain disorders, and cancers.
• More often than not, the images from a PET scan are clubbed with CT and MRI scans for creating special graphical representations.
