评价超声与磁共振胰胆管成像诊断胆系疾患的价值

目的探讨超声(US)及磁共振胰胆管成像(MRCP)技术在胆系疾病中的诊断价值。方法87例胆系疾病患者行US及MRCP检查,结果应用SPSS10.0进行接受器工作特性曲线(ROC)分析,所有病例经内窥镜逆行胰胆管造影(ERCP)或手术证实。结果对于胆囊及肝内胆管疾患,US及MRCP的ROC曲线下的面积相近,无明显差异(P=0.326;P=1.000);而对于胆总管疾患,MRCP的ROC曲线下面积大于US曲线下面积,具有差异显著性(P=0.034)。结论MRCP与US在诊断胆囊及肝内胆管疾患方面具有同样高的诊断价值,而在诊断胆总管疾患方面MRCP的价值优于US。

Evaluation of Ultrasound and MRCP in the Diagnosis of Biliary System Diseases

Objective To evaluate the value of Ultrasound(US)and Magnetic resonance cholangiopancreatography(MRCP)in patients with biliary system diseases.Methods US and MRCP were performed in 87 patients who were suspected as biliary system diseases.All the patients obtained the final diagnosis via endoscopic retrograde cholangiopancreatography(ERCP)or surgery.The performance of MRCP and US was determined by ROC curves.Results ROC analysis showed that there was no significant difference in the diagnosis of gall bladder and intraheptic biliary system diseases between MRCP and US (P=0.326 and 1.000,respectively).There was a statistically significant difference between MRCP and US in the detection of common bile duct (CBD) diseases (P=0.034).Conclusions MRCP has the same important value as US in the diagnosis of biliary system diseases,but is better in the intraheptic biliary system diseases.
