WebThose abbreviations stand for: fluorodeoxyglucose (FDG)-positron emission tomography (PET). The role of this procedure is to detect metabolically active malignant lesions including lung cancer, colorectal cancer, lymphoma, melanoma, breast cancer, ovarian cancer, brain cancer and multiple myeloma. WebThe PET scan reveals which areas of the brain are burning the most sugar. The results of PET scans can show small areas of activity. For example, researchers viewing some of the first PET scans were excited to see different areas of a rat cortex light up according to which of five separate whiskers was touched.
WebAlso PET doesn't necessarily have to use glucose, it can use any molecule with a radioactive tag! People often use PET-amyloid scans to diagnose Alzheimer's, which is correlated with the buildup of a protein called amyloid-beta in the brain. PET-amyloid scans allow you to see where and how much amyloid is in the brain. WebPET is a brain imaging technique that was still quite new in the 1990s. It involves injecting the participant with a glucose solution that dissolves in the blood. This glucose solution has been “tagged” with a radioactive tracer which will make its way to the brain. This takes about half an hour. "Radioactive tracer" sounds pretty scary.
