摘要 目的:探讨胰胆管水成像(MRCP)结合扩散加权成像(DWI)对胆道梗阻性疾患诊断的临床实用价值。方法:对110例经病理证实的良恶性胆道梗阻病例的MRCP及DWI进行回顾性分析,其中胆道结石65例;肝门部胆管良性狭窄11例,壶腹部癌及胰头癌21例;肝门部癌13例。结果:110例胆道梗阻性病例中,经MRCP检查对胆道梗阻性扩张均显示明确,梗阻部位均能准确定位;其中胆道结石于MRCP原图及三维重建图显示清晰,均表现为低信号影,在DWI中呈低信号;胆道肿瘤性病变在MRCP中梗阻征象及梗阻部位显示清晰;胆道肿瘤性病变在DWI中呈高信号,显示清晰;胆管炎性狭窄在MRCP中梗阻征象及部位显示明确,在DWI中呈等信号。结论:在进行MRCP检查的同时,辅以DWI检查有助于提高胆道梗阻性疾患诊断的准确性。应用MRCP结合DWI应成为诊断胆道梗阻性疾患的推荐方法。
