Abstract

Objective To explorate the value of MRCP combined with high resolution DWI qualitative in diagnosis of non calculus of extrahepatic bile duct obstructive disease. Methods 52 cases of non calculus of extrahepatic bile duct obstructive disease in the Department of hepatobiliary surgery in our hospital were retrospectively analyzed, and they were randomly divided into two groups: The control group were diagnosed by simple MRCP and the research group by MRCP combined with high resolution DWI qualitative. We compared the accuracy of qualitative analysis of two groups , the examination results were analysis as well. Results The control group for the diagnosis of common bile duct carcinoma, ampullary carcinoma, duodenal papillary carcinoma, duodenal papillitis cholangitis, the coincidence rate was 66.67%, 100%, 40%, 50%, 66.67%, 61.54%, while the research group were 100%, 100%, 66.67%, 100%, 100%, 80%, 92.31%; research group total coincidence rate was 92.31% 61.54%, significantly higher than the control group, with significant difference (X2 =5.6841, P=0.0354); these two approaches can reflect the disease imaging features. Conclusion MRCP combined with high resolution DWI has high accuracy on non calculus of extrahepatic bile duct obstructive disease diagnosis,which worth to promote in clinic.
