title: Abdomen: normal variations and benign conditions resulting in uptake on FDG-PET/CT.
abstract: The increasing use of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in oncology has led to: improved sensitivity and specificity in detecting localized and metastatic disease, increased ability to target biopsies to the site of most aggressive disease, and development of a noninvasive biomarker to assess prognosis and effects of therapy. However, for correct interpretation of FDG-PET/CT studies, an understanding of both normal and abnormal imaging appearances commonly encountered in oncology patients is important. This article discusses commonly seen normal variations and benign findings on FDG-PET/CT of the abdomen.
