胆管梗阻低场MRI和CT检查结果对比分析

【摘要】 目的:探讨低场MRI在胆管梗阻中的应用。方法:收集我院收治的胆管梗阻患者84例,对其MRI资料进行回顾性分析。结果:本组84例梗阻部位定位准确,定位诊断准确率为100%。MRI诊断胆管梗阻明显优于CT检查。MRI系统显示胆道满意,有55例恶性胆管梗阻,图像可见卫星结节、中心瘢痕、增强后呈中度环形强化。表现为肝内块状T1WI低信号、T2WI高信号。其中3例呈梗阻端杯口状、5例呈萝卜根样、22例呈鸟嘴样、25例呈截断状。84例中胆管图像呈枯枝状,胆管直径:6～10mm,为中度扩张,共有34例;有50例胆管直径>10mm,胆管图像呈腊肠状,为重度扩张。扩张的肝内胆道均呈为"软藤"状。下段胆管癌的胰管扩张,呈现为"双腔"征。结论:MRI对胆道梗阻性疾病定位准确,特异性高,是诊断胆道梗阻性疾病定的有效方法。更多还原
