摘　　要：目的:比较螺旋CT、低场强MRCP、US对低位胆道梗阻的临床诊断价值。方法:收集经手术与病理证实的130例低位胆道梗阻病例,对其低场强MRCP、螺旋CT、US影像表现进行回顾性分析。结果:130例低位胆道梗阻中结石58例、胆管癌12例、壶腹癌24例、胰头癌26例、胆管炎10例。螺旋CT、MRCP、US对低位胆道梗阻定位诊断准确率分别为90.77%、98%、81.54%。定性诊断准确率分别为83.08%、73.38%、50.77%。薄层螺旋CT能显示梗阻端的肿块、胆管壁规则或不规则增厚,对壶腹癌和胆管癌的确诊率较高(83.33%、66.67%)。MRCP能显示胆胰管下段梗阻的各种异常改变,对胰头癌及结石的确诊率(92.31%、89.66%)高于CT和US。结论:螺旋CT与MRCP对不同性质病变的低位胆道梗阻具有不同的定性诊断价值。CT与MRCP结合可提高定位定性的准确性,US受肠气的影响确诊率较低。Objective To evaluate the value of Spiral CT , Low Field MRCP, US in diagnosis of low level biliary obstructive diseases. Methods The dete of Spiral CT and MRCP and US of 130 patients with low level biliary obstructive confirmed by pathology were analyzed retrospectively. Result of 130 cases of low level biliary obstructive disease, 58 were cholelithiasis, 12 were carcinoma of bile bnct, 24 were ampullary carcinoma, 26 were carcinoma of heakd of pancreas, 10 were. The accuracy of diagnosing location of low level obstruction with Spiral CT and MRCP and US were 90. 77%, 98% and81.54% respectively. The accuracy of diagnosis of nature of low level obstruction were 83. 08%, 73. 38, and 50. 77% respectively. Conclusion the Spiral CT and MRCP were provided with different value for determining the different nature of low level biliary obstructi. Conventional CT in combination Whih MRCP can increase the accuracy of diagnosis of location and nation of the diseases. The yate of diagnose of the US was lower as the inheetion of flatus.
