PET/computed tomography (CT) combines the anatomic information from CT with PET metabolic characterization. 18F-fluorodeoxyglucose (FDG) PET is helpful to differentiate malignant lesions from benign ones, that usually show lower or no uptake. However, active inflammation or infectious disease might also present FDG uptake. Studies confirm the great value of PET/CT as the imaging method of choice for guiding biopsy procedures. Novel PET radiopharmaceuticals are also being investigated for guiding biopsies.
