CT与MRI联合MRCP对胆道梗阻病变定性诊断准确率的影响

Effect of CT and MRI Combined with MRCP on the Accuracy of Qualitative Diagnosis of Biliary Obstruction

目的:探讨CT与MRI联合磁共振胰胆管造影(MRCP)在胆道梗阻病变定性诊断中应用价值。方法:选取许昌市中医院65例胆道梗阻病变患者,均行CT、MRI+MRCP检查,统计不同检查方法对良恶性病变定性诊断结果。结果:CT对胆道梗阻病变准确定性55例,定性诊断准确率为84. 62%(55/65),MRI+MRCP对胆道梗阻病变准确定性59例,定性诊断准确率为90. 77%(59/65),组间比较差异无统计学意义(P> 0. 05); CT+MRI+MRCP对胆道梗阻病变定性诊断准确率为98. 46%(64/65),高于CT诊断84. 62%(55/65),差异具有统计学意义(P <0. 05)。结论:CT联合MRI+MRCP可提高胆道梗阻病变定性诊断准确率,作为临床诊治疾病的依据。

Objective: To investigate the application value of CT and MRI combined with magnetic resonance cholangiopancreatography( MRCP) in the qualitative diagnosis of biliary obstruction. Methods: A total of 65 cases of biliary obstruction in Xuchang Hospital of Traditional Chinese Medicine were selected and examined by CT and MRI + MRCP.The results of qualitative diagnosis of benign and malignant lesions by different methods were statistically analyzed. Results:CT accurately identified 55 cases of biliary obstruction,the accuracy rate of qualitative diagnosis was 84. 62%( 55/65),and59 cases were accurately diagnosed by MRI + MRCP for biliary obstruction,and the accuracy rate of qualitative diagnosis was90. 77%( 59/65). There were insignificant differences between two groups( P > 0. 05). The accurate diagnostic rate of CT+ MRI + MRCP for biliary obstruction was 98. 46%( 64/65),higher than that of CT 84. 62%( 55/65),and the difference was statistically significant( P < 0. 05). Conclusion: CT combined with MRI + MRCP can improve the accuracy of qualitative diagnosis of biliary obstruction,which is a basis for clinical diagnosis and treatment of diseases.
