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

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.
