Abstract: Objective To analyse MRI and MRCP features of primary gallbladder carcinoma.Methods MRI and MRCP data of 87 cases with gallbladder carcinoma confirmed by operation and pathology were studied retrospectively.Results Four patterns of gallbladder carcinomas were found by MRI:wall thickening (35 cases),papillary nodular(17 cases),mass-type (25 cases) and mixed (wall thickening and nodular) (10 cases).Pathology showed the tumors in combination with chronic cholecystitis and cholecystolithiasis in 69 cases(79.31%).In comparison with that of operations,the accurate diagnostic rates were 46/50(92%) with MR imaging,13/19(68.4%) with MRCP and 80/82(97.6%) in combination with both MR imaging and MRCP.The other features included:hepatic invasion directly by gallbladder cancer in 25/32(78.12%),liver metastases in 17/19(89.47%),lymph node metastases in 28/34(82.35%),intra-adbominal distant metastases in 13/13(100%) and invasion of bile ducts in 25/26(96.15%).Conclusion MRI combined with MRCP is of significant value in diagnosing gallbladder carcinoma.
