目的探讨CT与MRI检查对自身免疫性胰腺炎(AIP)的诊断价值。方法回顾性分析2011年6月至2013年12月期间眉山市中医医院收治的14例AIP患者的临床和影像学资料。结果 CT和MRI检查示AIP患者的胰腺弥漫性肿大呈腊肠状,T1WI示胰腺实质信号明显减低,扩散加权成像(DWI)示胰腺实质信号明显增高;增强扫描后动脉期胰腺实质强化幅度明显降低,延迟期呈持续性延迟强化伴包膜征,胆总管胰腺段呈鸟嘴样狭窄。结论 AIP的影像学表现具有一定的特征性,结合临床表现及实验室检查可早期诊断,对选择治疗方案具有重要意义。
Objective To investigate the diagnostic value of CT and MRI in the diagnosis of autoimmune pancreatitis (AIP). Methods The clinical and imaging data of 14 AIP patients admitted to Meishan Chinese Medicine Hospital from June 2011 to December 2013 were retrospectively analyzed. Results CT and MRI showed that the diffuse pancreas of AIP patients was sausage-like. The real signal of pancreas was significantly decreased on T1WI, and the real signal of pancreas was significantly increased by diffusion weighted imaging (DWI). The extent of parenchymal enhancement of pancreas in arterial phase was significantly lower after enhanced scan , Delayed delay was enhanced with persistent capsule signs, common bile duct pancreatic segment was beak-like stenosis. Conclusion The imaging findings of AIP have certain characteristics. Combined with clinical manifestations and laboratory tests can be early diagnosis, which is of great significance for the selection of treatment options.
