摘　　要：目的　探讨磁共振胰胆管成像和脂肪抑制技术在壶腹周围癌诊断中的价值。方法　对 3 7例胰头癌、胆总管下端癌、Vater’s壶腹癌及十二指肠乳头癌分别进行T1WI/SE、T2WI/TSE、脂肪抑制技术 (FST)序列和MRCP检查 ,并全部经手术病理证实。结果　MRCP在壶腹周围癌定位的准确率为 86.49% ,定性的准确率为 78.3 8% ;MRCP结合脂肪抑制技术可使胰头癌定性的准确率达 10 0 %。胰头癌的“双管征”多呈分离状态 (占 5 7.14 % ) ,壶腹癌的“双管征”多呈并行状态 (占75 % )。 2 1例胰头癌脂肪抑制技术所有肿瘤均呈低信号改变。结论　MRCP对壶腹周围癌的定位准确性较高 。Purpose To evaluate the diagnostic value of periampullary carcinoma by magnetic resonance cholangiopancreatography and FST. Methods Thirty seven cases with pancreatic head carcinoma,common bile duct lower carcinoma,ampullar carcinoma and duodenal papilla carcinoma were examined by T1WI/SE,T2WI/TSE,FST and MRCP.All the cases were proved by operation. Results The accuracy of MRCP for obstructive level was 86.49%.The specificity for the cause of obstruction was 78.38%.Combining with FST,the nature of obstruction was 100%.The 'double barrelled sign' of pancreatic head Carcinoma was separate (57.14%). The 'double barrelled sign' of ampullar carcinoma was side by side.On FST 21 cases with pancreatic head Carcinoma appeared hypo intensity. Conclusion MRCP examination has a high accuracy for the level of the obstructions,while combining with FST canfurther improve the accuracy of MRCP for the nature of the obstructions.
