目的:探讨MRI不同检查方法对十二指肠乳头旁憩室(periampullary diverticulum,PAD)的诊断价值。方法:应用MRI多序列检查方法诊断PAD23例,并进行分析。结果:T1WI显示为囊状低信号影,与十二指肠相通者1例,其余22例表现为不均匀略低及高低混杂信号,均未明确诊断;横断位压脂T2WI显示含气液平面囊性病灶15例;冠状位FIESTA序列表现为混杂高信号或高信号影15例;呼吸触发3D MRCP表现为高或混杂高信号影16例;冠状位屏气3DCE LAVA动态增强扫描均清晰显示。其中合并胆系结石13例,胆系炎症及感染13例,胰腺炎3例,胆胰管扩张3例,十二指肠炎症3例。结论:MRI能多序列、多方位、直观、无创的清晰显示PAD的部位、大小、范围及与邻近结构的关系,同时显示胆胰疾病形态学改变。故MRI多序列检查非常必要,是PAD诊断及鉴别诊断的重要方法。
