摘要 目的:探讨自身免疫性胰腺炎(AIP)的^(18)氟—脱氧葡萄糖(^(18)F-FDG) PET/CT及MRI影像特征和应用价值。方法:回顾性分析2014年1月至2017年12月广西医科大学第四附属医院收治的经病理或临床随访证实的10例AIP患者MRI影像资料,其中8例同期行^(18)F-FDG PET/CT检查。结果:MRI表现:胰腺弥漫增大6例,局限性肿大4例;T1WI、T2WI呈等信号或信号轻度增高;在抑脂T1WI上病变信号欠均匀;动态增强扫描时6例呈索条状、细小结节状渐进性强化;病变区均未见胰管显示,病变区远端胰管呈轻度串珠样扭曲扩张,3例合并胆管轻度扩张。^(18)F-FDG PET/CT表现:胰腺弥漫性代谢增高4例,而局部代谢增高4例,其中1例呈"空腊肠"征,2例呈"链条"样改变,1例呈"煎蛋"征。结论:AIP的MRI及^(18)F-FDG PET/CT影像表现具有一定特征性,对AIP的诊断具有重要的应用价值。
