MR cholangiopancreatography in comparison with ultrasound in the diagnosis of choiangiopancreatic disease / 中国普通外科杂志

ABSTRACT

Objective To evaluate the diagnostic value of MRCP compared with ultrasound in patients with cholangiopancreatic disease by ROC curve. Methods The data of 62 patients with suspected cholangiopancreatic disease undergoing both MRCP and ultrasound were retrospectively studied. ROC analysis was performed by ROCKIT software. Results Area under the ROC curve of MRCP was 0.739. Area under the ROC curve of US was 0. 930. ROC analysis showed that these two modalities were effective in diagnosing cholangiopancreatic disease, with MRCP being more effective than ultrasound, especially for the diagosis of lower biliary tract diseases. Conclusion MRCP combined with MRCP source images is of great help in the diagnosis of pancreaticobiliary duct diseases.
