PET scanner creates an image of your body’s metabolism of a radio-active (or radio-tracer) material called FDG (F18-fluorodeoxyglucose), which is similar to glucose. For the scan you will receive an intravenous (IV) injection of small amount of FDG. Cancer cells metabolize glucose (and FDG) at a higher rate and PET scan shows this as abnormal activity.
A CT scanner uses x-rays to make an image of the sections of your body. The scan shows your body’s organs, bones and tissues in greater detail. For the CT scan, you will receive a contrast agent intravenously and orally. These help produce even clearer image.
When both PET and CT scanning are performed simultaneously, the information about function and structure are integrated through computer models to give a great deal of detailed information. Our scanner is the state-of-the-art Seimens, “Biograph” machine.
