磁共振胰胆管水成像与内镜逆行胰胆管造影在阻塞性黄疸病因诊断中的对比研究

目的探讨磁共振胰胆管水成像(MRCP)与内镜逆行胰胆管造影(ERCP)对阻塞性黄疸病因诊断的应用价值。方法对358例临床诊断为阻塞性黄疸病例行MRCP和ERCP检查。对MRCP和ERCP结果与临床/病理诊断比较,对比2种检查方法差异。结果 MRCP诊断梗阻病因与临床/病理对比,准确率90.8%;ERCP诊断梗阻病因与临床/病理对比,准确率98.0%。结论MRCP在阻塞性黄疸的病因诊断中具有较高价值,可作为阻塞性黄疸的首选检查和ERCP的术前筛选,是一种可靠、安全、无创的检查技术。

Comparative study of magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancre-atography in the etiological diagnosis of obstructive jaundice

Objective To investigate the clinical value of magnetic resonance cholangiopancreatography(MRCP) and endoscopic retrograde cholangiopancreatography(ERCP) in the etiological diagnosis of obstructive jaundice.Methods Three hundred and fifty-eight patients that diagnosed as obstructive jaundice carried out MRCP and ERCP.To contrast the difference between the result of MRCP and ERCP with diagnosis of pathologic and clinical.Results Comparing with pathologic diagnosis or clinical diagnosis,the accuracy rate of MRCP in the etiological diagnosis of obstructive jaundice was 90.8%,the accuracy rate of ERCP in the etiological diagnosis of obstructive jaundice was 98.0%.Conclusion MRCP is good at evaluating the etiological diagnosis of obstructive jaundice.It is a kind of reliable,safe and non-invasive technique,which can be used as the first-elected method before ERCP.
