ABSTRACT
Objective To evaluate the value of imaging means on preoprative diagnosis for patients with malignant obstruction of the biliary and pancreatic ducts.[WT5”HZ]Method [WT5”BZ]44 cases underwent preoperative MR/MRCP/MRA examination. The accurate rate of diagnosis was compared with that derived from B us, CT and ERCP. Results 28 of 44 cases were diagnosed as with pancreatic and periampullary carcinoma, 5 cases as with pancreatic body and tail carcinoma,11 cases as with biliary duct carcinoma. The accurate rates of MR/MRCP/MRA for tumor locating and cause were 100% and 96% respectively. Blood vessel invasion, adjacent organ infiltration and matastasis were detected preoperatively in 17 cases. In contrast, the accurate rate for tumor locating and cause were 82% and 76% with CT, 73% and 68% with B us, 96% and 84% with ERCP. [WT5”HZ]Conclusions [WT5”BZ] MR/ MRCP /MRA combined has advantage over B us, CT and ERCP in preoperative diagnosis especially for detecting organ matastasis and blood vessel infiltration. It has an important value in the establishment of tumor staging and decision making of clinical therapy.
