    MRCP联合MRI冠状位成像在胆管梗阻中的诊断价值

    Diagnostic value of MRCP combined with coronal MRI in the biliary obstruction

      摘要
    • 摘要:
      目的探讨磁共振胰胆管成像(magnetic resonance cholangiopancreatography，MRCP)联合磁共振冠状位成像在胆管梗阻中的诊断价值。
      方法选择经病理证实的70例胆管梗阻性黄疸病人作为研究对象，所有病人术前均进行MRCP及MRI冠状位成像(平扫+增强)序列扫描，分析MRCP、MRI冠状位及两者联合3组检查方法对胆管梗阻的定位及定性诊断准确率。
      结果3组检查方法对胆管梗阻的定位诊断准确率差异无统计学意义(P>0.05)；对胆管梗阻的定性诊断准确率分别为71.4%、82.9%、94.3%，联合检查准确率高于MRCP、MRI冠状位单一检查方法，差异有统计学意义(P < 0.05)，其中良性胆管梗阻的定性诊断准确率差异无统计学意义(P>0.05)，恶性胆管梗阻的定性诊断准确率分别为58.7%、78.3%、93.5%，联合检查准确率高于MRCP、MRI冠状位单一检查方法，差异有统计学意义(P < 0.01)。
      结论在胆管梗阻的定位诊断方面，MPCP与MRI冠状位成像均有较高的诊断准确性；在胆管梗阻的定性诊断方面，MRI冠状位对恶性梗阻的定性诊断准确性优于MRCP序列，且两者联合可显著提高对胆管梗阻的定性诊断，为临床明确梗阻性黄疸的病因提供较高价值的参考依据，值得推广使用。

       

      Abstract:
      ObjectiveTo investigate the diagnostic value of magnetic resonance cholangiopancreatography(MRCP) combined with the coronal magnetic resonance imaging(MRI) in the biliary obstruction.
      MethodsSeventy patients with obstructive jaundice confirmed by pathology were selected as the subjects, and all patients were detected using MRCP and coronal MRI(plain scan+ enhancement) scanning before operation.The accuracy of the positioning and qualitative diagnosis of biliary obstruction using MRCP, MRI coronal examination and combination of MRCP and MRI were analyzed.
      ResultsThere was no statistical significance in the accuracy of positioning diagnosis of biliary obstruction among three groups(P>0.05).The qualitative diagnosis accuracy rate of the MRCP, MRI coronal examination and combination of MRCP and MRI in biliary obstruction were 71.4%, 82.9% and 94.3%, respectively, and the accuracy of combined examination was higher than that of MRCP or MRI coronal exmination alone(P < 0.05).There was no statistical significance in the accuracy of qualitative diagnosis of benign biliary obstruction among three groups(P>0.05).The accuracy of qualitative diagnosis of the MRCP, MRI coronal examination and combination of MRCP and MRI in malignant biliary obstruction were 58.7%, 78.3% and 93.5%, respectively, and the accuracy of combined examination was higher than that of MRCP or MRI coronal exmination alone(P < 0.01).
      ConclusionsIn the localization diagnosis of biliary obstruction, the diagnostic accuracy of MPCP and MRI coronal imaging are high.The qualitative diagnosis of MRI coronal position in malignant obstruction is better than that of MRCP sequence.The combination of MPCP and MRI coronal imaging can significantly improve the qualitative diagnosis of biliary obstruction, which can provide a valuable reference basis for the clinical determination of the etiology of obstructive jaundice, and is worthy of promotion and use.
