Question

Fluorodeoxyglucose (FDG), incorporating the positron emitter fluorine-18, is a commonly used radioisotope in PET scans. Which of the following statements about PET scans is correct? Select one: a. FDG is an analogue of glucose, so areas of low activity in a PET scan indicate areas of high glucose metabolism b. FDG in solution is injected into vascular system, so areas of high activity in a PET scan indicate areas of high vascularization c. FDG is metabolized by tumour cells more readily than standard glucose, so areas of high activity in a PET scan indicate tumour cell locations d. FDG is an analogue of glucose, so areas of high activity in a PET scan indicate areas of high glucose metabolism
