Pet Scan Side Effects
Low Risk - Headache: Florbetapir f18 (trade name amyvid) is a new pet imaging agent that helps to diagnose alzheimer's disease. From the clinical trials, side effects (also called adverse reactions) were quite unusual, with no serious ones. The most common side effect was headache, occurring in 1.8% of the patients. Next was musculoskeletal pain (0.8%), followed by nausea and fatigue (each at 0.6%). ...Read moreSee 2 more doctor answers
Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more

What is the question: Currently pet scans are widely use for evaluation of glucose metabolism in the body. In oncology, is use to for initial metabolic characterization of tumors, metastases as well as for treatment response and surveillance. In cardiology, pet scans are use to assess heart ischemia and viability and in neurology the study is use to evaluate cognitive disorders, epilepsy and brain tumors ...Read moreSee 2 more doctor answers
Positron Emission: These studies are done by injecting a special "dye" that is attached to a specific molecule. Most of the pet today is done using FDG (a glucose/sugar look-a-like molecule). Wherever this molecule is used/concentrated, the pet scan is brighter. Hence, tumors/infections (which use a lot of energy/sugar/fdg) are bright on such studies.
