Abstract Purpose In this retrospective study, we evaluated the diagnostic value of [18F]FDG PET/CT in preoperative assessment of extrahepatic cholangiocarcinoma (ECC) and to develop a PET-based diagnostic algorithm for ECC. Material and Methods Patients with suspected ECC with biliary obstruction were included. Patients received [18F]FDG PET/CT scan and image analysis. FDG uptake was semi-quantified using the SUVmax of the suspected primary tumor, lymph nodes and metastatic lesions. Sex, age, tumor location, enhancement patterns and tumor size were analyzed using binary logistic regression for prediction of ECC…
