ABSTRACT
Objective To explore the value of magnetic resonance cholangiopancreatography (MRCP) and MRI in the diagnosis and differential diagnosis of periampullary carcinoma. Methods Plain and dynamic multi-phase enhanced MRI data of 54 patients with periampullary carcinoma proved by pathology were retrospectively analysed. χ~2 test and two independent samples t test were used to examine the relative results. The results of MRI were compared with that of pathology. Results Of 32 cases with carcinoma of head of pancreas, 7 cases (21.9%) exhibited "four-duct sign". 16 cases were carcinomas of the lower part of common bile ducts, 9 cases (56.3%) showed "three-duct sign". The difference between carcinomas of head of pancreas and carcinomas of the lower part of common bile ducts was significant (P<0.05). Additionally, the ratio of the largest area of masses and the diameter of com-mon bile duct in pancreatic cancer tumors was larger than that in common bile duct cancer (P<0.05) for whether the intraoperative or MRI measurement. Conclusion MRI and MRCP are very helpful in diagnosis of periampullary carcinoma.
