超声与磁共振胰胆管成像诊断梗阻性黄疸对比研究

摘要

目的 评价超声(US)与磁共振胰胆管成像(MRCP)对梗阻性黄疸的诊断价值.方法 收集本院通过临床随访观察或手术病理证实梗阻性黄疸患者454例,US检查213例,MRCP检查241例.结果 US及MRCP对显示引起梗阻性黄疸的不同病变有不同特点.US及MRCP对胆总管结石及壶腹癌有统计学差异(P＜0.01).结论 US可作为显示梗阻性黄疸的首选筛查方法,MRCP有较高的诊断价值.%Objective To determine the value of ultrasonography(US) and magnetic resonance cholangiopancreatography(MRCP) in the diagnosis of obstructive jaundice.Methods The data of 454 cases(213 cases underwent US,241 cases underwent MRCP) with obstructive jaundice confirmed by clinical or surgery and pathology in our hospital were be collected and analyzed.Results US and MRCP had different characteristics in displaying the different lesions caused obstructive jaundice.There were statistically significant differences for the diagnosis of obstructive jaundice and common bile duct stone and carcinoma of ampulla between US and MRCP (P＜ 0.01).Conclusion US should be the first choice of screening for the diagnosis.MRCP is valuable in differential diagnosis.
