Methods Eighty-four subJects included 5O normal individuals and 34 patlents(22 patients investlgated for pancreatic neopIasia and 12 pancreatitis) were presented. The MR protocol inc1uded conventional SE T1WI, FSE T2WI, Pre-and post-contrast T,-weighted fat-suppressed and GRE imaging. ResuIts The best diagnostic information was provided by Tl-weighted fatsuppressed imaging before and after gadolinium enhancement on 27 of 34 cases with abnorm8I pancreas, followed by immediately postcontrast GRE images. Precontrast GRE imaging better showed the features of acute pancreatitis. FSE T2WI obviously exhibited lsiet cell tumor and metastases of Iiver from pancreatic adenocarcinoma. Conclusion The standard MR protocol included T1-weigkted fat-suppressed image and dynamic GRE imaging.展开更多
