超声、CT及MR在诊断胰头壶腹癌中的对比价值

Ultrasound,CT and MR Contrast Value in the Diagnosis of Pancreatic Cancer and Ampullary Cancer

目的:探讨超声、CT及MR在诊断胰头壶腹癌中的临床价值。方法:回顾性分析选取本院2009年2月-2014年3月经手术病理确诊胰头壶腹癌的患者40例,分别采用超声、CT及MR的影像学检查分析,通过以上分析方法比较得出最佳检查方法。结果:超声确定胰头癌人数18例、壶腹癌5例,胆总管末端癌3例、十二指肠乳头癌0例;CT确定胰头癌人数20例、壶腹癌5例,胆总管末端癌3例、十二指肠乳头癌2例;MR确定胰头癌人数22例、壶腹癌9例,胆总管末端癌5例、十二指肠乳头癌1例。40例胰头壶腹癌,超声、CT及MR诊断准确的分别为26例、30例、37例,诊断准确率分别为65.0%、75.0%、92.5%,MR诊断准确率明显高于超声及CT,比较差异有统计学意义(P<0.05);超声与CT诊断准确率比较,差异无统计学意义(P>0.05)。结论:超声可作为梗阻性黄疸定位诊断的首选检查方法;超声联合CT、MR检查可有效提高胰头壶腹癌的诊断率。

Objective：To investigate the ultrasound,CT and MR clinical application in the diagnosis of pancreatic cancer and ampullary cancer.Method：To analyze retrospectively the imaging findings in 40 cases with pancreatic cancer ampullary ultrasound,CT and MR,and compared the best screening method.Result：40 cases with pancreatic cancer ampulla,ultrasound,CT and MR diagnostic accuracy were 26 cases,30 cases,37 cases,the diagnostic accuracy rates were 65.0%,75.0%,92.5%.Conclusion：Ultrasound can be used as the preferred screening method in diagnosis of obstructive jaundice;ultrasound combined with CT,MR examination can effectively improve the diagnosis of pancreatic ampullary cancer.
