摘　　要：目的探讨常规MR、动态增强扫描(THRIVE)联合磁共振胰胆管造影(MRCP)对自身免疫性胰腺炎的诊断价值。方法对经临床证实的18例自身免疫性胰腺炎进行回顾性分析,18例均行MR平扫及动态增强扫描检查、MRCP检查。结果胰腺弥漫性受累(12/18),胰头局限性肿块(4/18),胰体尾部受累(4/18);12例可见"假包膜"征。MRCP:14例胆总管胰腺段狭窄,13例见胰管局限性或弥漫性狭窄,4例主胰管未见显示;动态增强后病变区呈延迟性强化。结论常规MRI、动态增强扫描联合MRCP的联合应用对自身免疫性胰腺炎的诊断有重要价值,其影像学结果对临床治疗决策有指导意义。Objective To explore the diagnosis value of MR, combination of THRIVE and MRCP in autoimmune pancreatitis （AIP）. Methods 18 cases with AIP were retrospectively reviewed. All cases were examined by plain MR scanning, dynamic enhanced scanning and MRCP. Results 12 cases showed diffuse involvement of pancreas, 4 cases showed localized tumor of the pancreatic head. 4 cases showed involvement of pancreatic tail. 12 cases showed psuedocapsule. Examining by MRCP, 14 cases showed pancreatic stenosis of choledoch, 13 cases showed localized and diffuse stenosis of pancreatic duct, 4 cases of main pancreatic duct were invisible. Delayed reinforcement was found on lesions after dynamic enhancement. Conclusion Application of combination of MRI, THRIVE and MRCP has an important value for diagnosis of autoimmune pancreatitis. The imaging results is of great significance in clinical decision making.
