Prognostic Value of the Preoperative Tumor-to-Blood Pool Standardized Uptake Value Ratio Derived From FDG-PET/CT in Distal Bile Duct and Ampullary Cancers.

PURPOSE This study investigated the prognostic value of the preoperative tumor-to-blood pool standardized uptake value ratio (TBR) on 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in patients undergoing pancreatoduodenectomy (PD) for distal bile duct and ampullary cancers. METHO...

Multi-pool Model-based Amide Proton Transfer Imaging for Tumor Characterization and Risk Stratification in Endometrial Carcinoma.

PURPOSE To evaluate whether multi-pool model (MPM)-based amide proton transfer (APT) imaging parameters can assess histological grade, histological type, lymphovascular space invasion (LVSI), and recurrence risk in endometrial carcinoma (EC), relative to conventional apparent diffusion coefficient (ADC) and magnetizati...
