Abstract
Objective To evaluate the value of five imaging methods in the diagnosis of ampullary carcinoma. Methods Clinicopathologic data like BUS, CT, MRI, MRCP and ERCP of 264 patients with ampullary carcinomas confirmed by operation and pathology between January 1993 and December 2008 were retrospectively reviewed. Retrospective comparative studies on the diagnostic value of BUS, CT, MRI, MRCP and ERCP were initiated. Results The diagnose accordance rates of BUS, CT, MRI, MRCP, ERCP in detecting ampullary carcinoma were 33. 6％ (81/241), 52.6％ (120/228), 48.8％ (40/ 82 ), 42. 2％ ( 19/45 ) and 79. 5％ ( 120/151 ), respectively. The difference between each imaging method was significant ( F ＜0. 05 ). ERCP had a significantly higher diagnose accordance rate than other imaging methods ( P ＜0. 05 ). The diagnose accordance rate between CT and BUS had statistical difference ( P ＜0. 05 ). No significant differences were shown in diagnose accordance rate between CT, MRI and MRCP ( P ＞0. 05 ). Conclusion Each imaging methods has its advantages and disadvantages , it should be used rationally. BUS has lowest correctness for discovering ampullary carcinoma, but as a safe, quick and non - invasive examinational method, it may be the first choice for the diagnosis of ampullary carcinoma. CT had a much bettei diagnose accordance rate than BUS. No significant differences in diagnose accordance rate were found between CT, MRI and MRCP. ERCP is the most accurate method in the diagnosis of ampullary carcinoma, but it should not be used as a first-choice examination.关键词
