MRCP 2D FASE序列对低位胆道梗阻的诊断价值

MRCP 2D FASE sequence for diagnosis of the low-place obstruction of billiary tract

摘要: 目的: 评价磁共振胰胆管成像(MRCP)二维快速自旋回波序列(2D FASE)对低位胆道梗阻的诊断价值。方法: 采用TOSHIBA OPART 0.35T超导型磁共振,对30例低位胆道梗阻的患者行MRCP检查,并与手术和病理结果对照分析。结果: MRCP 2D FASE序列对低位胆道梗阻程度的判断和定位诊断准确率为100%,定性诊断准确率为83.3%,对结石和恶性胆道梗阻的诊断准确率分别为90%和80%。结论: MRCP检查成功率高,对各种胰胆管病变的临床应用适应证广泛,诊断价值可靠,是一种有效非侵入性的检查方法。

Abstract: Objective: To evaluate MR cholanglopan creatography(MRCP) in diagnosis of low-level biliary obstruction using two-dimensional fast spin-echo sequence (2D FASE).Methods: Thirty cases of low-level biliary obstruction were examined with TOSHIBA OPART 0.35T superconductive MRCP.The results were compared with the surgical and pathological findings.Results: The accuracy of MRCP in detecting the degree and location of bile duct obstruction was 100%.The accuracy of MRCP in detecting the cause of obstruction was 83.3%.In the diagnosis of choledocholithiasis and malignant bileduct obstruction,the accuracy of MRCP was 90% and 80%,respectively.Conclusions: MRCP examination has a high success rate and is adapt to extensive pancreaticobiliary duct diseases.It is a reliable and efficient non-invasive technique.
