How does the pet scan work
WebA PET scan measures metabolic activity in the body tissue’s cells. First, a small dose of radioactive glucose, a type of sugar referred to as the radiotracer, is administered intravenously. The PET scanner then takes images of where the glucose collects in the brain because they accumulate around malignant cells. WebWhat does PET scan show that CT does not? Perhaps the main difference between a CT scan and a PET scan is their focus. A CT scan creates a detailed non-moving image of organs, bones and tissues. A PET scan, on the other hand, shows doctors how the tissues in your body work on a cellular level.
