What Can A Pet Scan Show
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
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

Why would a pet scan show hyperactivity in an area in the colin where i had a polyp removed 2 months prior?
Possibly: Pet/ct scans with FDG localize areas with increased glucose metabolism. Although this can be some types of cancer, it also can be due to infection, inflammation and healing wounds. ...Read moreSee 2 more doctor answers
Glucose: Pet scan relies on the theory that tumors utilize a significant amount of glucose. Many different types of cancer can show up on pet scan but certain types of cancer are much more FDG avid. Low grade tumors usually have much less uptake than high grade tumors. In addition, mucinous neoplasms often do not have much FDG uptake. Small size tumors or micrometastases also may not show up on pet. ...Read moreSee 2 more doctor answers
Eyes to thighs: Even though the study is called whole body pet/ct, most often the image acquisition is from the eyes to thighs. The parts of the body that are included varies from center to center and also depends on the patient's symptoms and cancer histopathology. For e.g. Melanomas can metastasize anywhere in the body and thus real whole body scans are obtained (skull vertex to toes). ...Read moreSee 2 more doctor answers
Glucose metabolism: PET with F18 FDG, glucose metabolite, determines glucose metabolism of normal and abnormal structures.For example, sometimes lymph nodes are visualized on CT and do no know whether benign or malignant. In general malignant lesions are more active and have higher metabolism of glucose ...Read moreSee 2 more doctor answers
