摘　　要：目的评价多层螺旋CT双期增强扫描对胰头—壶腹区肿瘤的诊断价值。方法对29例经手术、病理证实的胰头—壶腹区肿瘤的螺旋CT平扫及双期增强扫描进行回顾性分析。结果9例胰头癌胰腺期胰腺—肿瘤密度差为(67±14)Hu,高于实质期的(36±19)Hu,差异有统计学意义(P<0.01);7例胰头段胆总管癌胰腺期肿瘤—胰腺密度差为(35±21)Hu,低于实质期的(57±18)Hu,差异有统计学意义(P<0.05);13例壶腹癌胰腺期胰腺—肿瘤密度差为(35±18)Hu,实质期为(30±17)Hu,差异无统计学意义(P>0.05)。结论多层螺旋CT双期增强扫描在胰头—壶腹区肿瘤的诊断与鉴别诊断中具有重要价值。Objective To evaluate the diagnostic value of dual phase enhanced MDCT on carcinoma of the pancreatic head and ampullary region.Methods Retrospectively analyzed the finding of dual phase enhanced MDCT in 29 cases of carcinoma of pancreatic head and ampullary region,which proved surgically and pathologically.Results In 9 cases with carcinoma of pancreatic head,the density difference of parenchyma to tumor attenuation（67±14） Hu was significantly higher than that in the pancreatic parenchyma phase（36±19） Hu（P0.01）.In 7 cases with cholangiocarcinoma of pancreatic segment maximal tumor,the density difference between pancreas attenuation and tumor was significantly lower in the pancreatic phase（35±21） Hu than in parenchyma phase（57±18） Hu（P0.01）.Besides,in 13 cases with carcinoma of ampullary,the density difference between pancreas attenuation and tumor was（35±18） Hu in pancreatic phase and（30±17） Hu in parenchyma phase,no statistical difference was proved（P0.05）.Conclusion The dual phase enhance MDCT played an important role in diagnosis and differential diagnosis the carcinoma of pancreatic head and ampullary region.
