目的　对胰腺癌的CT征象进行探讨。方法　收集经手术病理证实的胰腺癌18例，其中胰头癌13例，胰体癌3例，胰尾癌2例，就其CT征象进行分析，同时又收集手术病理证实的壶腹癌7例，十二指肠乳头癌5例，胆总管远端癌4例，胰头部炎性肿块3例作为鉴别诊断。全部病例均采用型高分辨率CT机作增强前后扫描，对兴趣区作3～5mm薄层和动态扫描，并分别摄取动脉期及静脉期相。结果　胰腺肿块呈低密度；胰头静脉弓扩大，胰后脂肪间隙模糊；肿块远端的胰腺组织不同程度稀疏、萎缩；肠系膜上动脉增粗；胆总管远端和主胰管远端间距分离；为胰腺癌较具特征的表现。结论　高分辨率CT薄层和动态扫描是发现胰腺癌的有效方法。

Objective 　To evaluate the CT manifestation of pancreatic cancer. Methods 　The CT signs of 18 cases of pancreatic cancer which include 13 cases of pancreas caput cancer,3 cases of pancreas corpus cancer and 2 cases of panceras cauda cancer were studied and compared with 7 cases of duct ampulla cancer,5 cases of duodenal papilla cancer,4 cases of inferior choledochus duct cancer and 3 cases of inflammatic mass in pancreatic caput.All of cases have pathologic results.The study were performed with plain and contrast scan with PQ－2000 CT set and then the 3～5mm thin slice dynamic study were performed in the ROI.The artery phase and venous phases were studied. Results　The characteristic signs of pancreatic cancer includes： no enhancement of pancreas mass;pancreas atrophy inferior mass;enlargement of venous arch of pancreas caput and superior mesenteric artery;obscure retropancreas space and distance increasing between inferior choledochus duct and proximal pancreatic duct. Conclusion　It is valuable to diagnosis of pancreatic cancer with HRCT.
