Abstract： 目的探讨原发输尿管癌的MR检查方法、影像表现并与其他影像方法比较,评价其临床价值.方法搜集近8年来手术治疗的原发输尿管癌87例,其中35例行MR检查.使用GE1.5 T MR机,所有病例先行冠状面重T2WI水成像以显示输尿管积水,如有梗阻则在梗阻水平行T2WI和T1WI扫描,其中11例进一步做了动态增强扫描.以手术所见和病理诊断为参照,对术前各种影像诊断的原始报告进行比较分析.结果35例中MRI显示33例患侧输尿管有不同程度积水,1例无异常发现,1例仅显示肾移植术后原肾萎缩改变.横轴面扫描33例有输尿管积水者中的32例在梗阻水平显示有异常软组织占位信号.增强扫描病灶呈逐渐、均匀的轻度或中等异常对比强化.同时期输尿管癌患者术前影像检查使用率依次为:B超(94.3%)、静脉肾盂造影(IVU,59.8%),CT(52.9%),MRI(40.2%)和逆行输尿管造影(RUP,35.6%).诊断准确率依次为:MRI(91.4%),RUP(80.6%),CT(63.0%),B超(47.6%)和IVU(11.5%).结论MR水成像与传统序列结合使用能清晰显示绝大多数有输尿管梗阻的原发输尿管癌病变,在常用的影像检查手段中诊断准确率最高,在B超筛查的基础上应作为首选.
