PET scan A procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is used. petroxannelolliadmanbifurcationoscanmucocelegaliumdotaredemonstratedscansuvtocmucin...
Since the turn of the millennium we are now using PET scans (which tag radioactive glucose metabolism) to evaluate the spread and activity of cancer. PET scans are more sensitive than other tests in evaluating cancer patients for many forms of cancer. Picture at the left is a PET scan show...
Positron emission tomography (PET) scan 正电子发射断层扫描(PET) Radioactive glucose is injected and then detected in the brain to image the metabolic activity of cells. PET scans provide valuable information about the function of brain tissue in p...

With cancer, these changes can occur before a mass or tumor starts to organize and form.About an hour before the exam, patients are given a small amount of radioactive glucose. The exam will reveal where the glucose has been metabolized, indicating the function and malignant potential of cance...
How does a PET Scan work? Before the examination begins, a radioactive substance (FDG) is produced in a machine called a cyclotron and attached, or tagged, to a natural body compound, most commonly glucose, but sometimes water or ammonia. Once this substance is administered to the patient,...
Nuclear medicine imaging procedures are primarily noninvasive and usually painless medical tests that use radioactive materials calledradiotracers. Radiotracers are designed to bond with certain chemicals within the body, like glucose, and highlight areas that are using those chemicals. ...
gamma rays: electromagnetic radiation emitted during radioactive decay and having an extremely short wavelength. glucose: a simple sugar that is a source of energy for the body and the only source of energy for the brain. positron emission tomography (PET): a nuclear medicine test in which ...
PET imaging or a PET scan, is a type of nuclear medicine imaging. In nuclear medicine, we use small safe amounts of radioactive material to diagnose or treat disease. This is a noninvasive procedure that is usually painless. Depending on your type of exam, you swallow, inhale or are inj...
