摘要: Radioiodine whole-body scintigraphy (WBS), which takes advantage of the high avidity radioiodine in functioning thyroid tissues, has been used for detection differentiated cancer. is a sensitive marker cancer; however, uptake not specific tissue. It can also be seen healthy tissue, including thymus, breast, liver, and gastrointestinal tract, or benign diseases, such as cysts inflammation, variety malignant non-thyroidal tumors, could mistaken In order to accurately interpret results, one must familiar with normal physiologic distribution tracer frequently encountered pathologic variants uptake. This article will provide systematic overview potential false-positive whole body illustrate how unexpected findings appropriately evaluated.
