What is Positron Emission Tomography?


Combine PET CT Scan

Positron emission tomography, also called a PET scan, is a nuclear medicine exam that produces a three dimensional image of functional processes in the body. A PET scan uses a small amount of a radioactive drug to show differences between healthy and diseased issue. The diagnostic images produced by PET are used to evaluate a variety of diseases. It can also show body functions such as blood flow, oxygen use and sugar (glucose) metabolism.

Combine PET/CT scans provide images that pinpoint the anatomic location of abnormal metabolic activity in the body. Together, the scans have been shown to provide more accurate diagnosis than the two scans separately.
