十二指肠慢性溃疡合并梗阻性黄疸的MRI表现

MRI Findings of Obstructive Jaundice Caused by Chronic Duodenal Ulcer

目的探讨十二指肠慢性溃疡所致梗阻性黄疸的MRI与磁共振胰胆管水成像(MRCP)表现。资料与方法回顾性分析经内镜检查或手术治疗证实的8例十二指肠慢性溃疡致梗阻性黄疸患者的MRI与MRCP表现。结果所有病例显示胆管梗阻位于十二指肠,壶腹部边缘光滑,十二指肠球部至降部较长范围羽毛状黏膜皱襞消失,管壁增厚,管腔变窄。结论十二指肠球部溃疡所致肠黏膜皱襞及肠腔、肠壁的MRI及MRCP改变,对诊断十二指肠溃疡所致梗阻性黄疸有较高的定性价值。
