Breast Cancer: PET/CT Imaging
PET/CT is a hybrid method that combines anatomical imaging with metabolic information in a single examination. Fluorodeoxyglucose (FDG) is a tracer, analog to glucose, that is mainly used, currently, for PET and PET/CT imaging. The role of FDG PET/CT is complementary to conventional imaging methods. The method has a limited role in the detection of primary breast cancer and locoregional staging. It may be useful in initial staging in patients with advanced disease and in assessment of tumor response to therapy. FDG PET/CT has been shown to be effective in early restaging of patients with breast cancer and is of great importance in patients with elevated tumor markers and negative or equivocal findings on conventional imaging techniques.
