摘　　要：目的:探讨64排CTA对胰腺癌的诊断及其与周围血管关系评估的价值。方法:对胰腺癌患者行64排CT动脉期和门静脉期增强扫描,进行胰周主要血管的CTA成像,判别胰腺癌发生位置及其与血管的关系,评价血管受侵的程度。结果:胰腺癌因发生位置不同容易侵及的胰周血管亦不同,胰周主要血管受侵包括CA5例,SA4例,SMA6例,PV5例,SV7例,SMV8例,血管侵犯征象包括包埋、浸润及栓子形成,管腔狭窄或闭塞。结论:64排CTA对胰腺癌的诊断及其与周围血管关系的评估具有重要价值,可作为手术可切除性判断的依据。Objective：To discuss the diagnostic value of pancreatic carcinoma and evaluate the relationship between tumor and vessels around by 64-detector CTA.Methods：Patients with pancreatic carcinoma performed contrast enhanced 64-detector CT scan with the arterial and portal vein phase.The CT angiography of the major peripancreatic vessels was made to detect the relationship between location of pancreatic carcinoma and peripancreatic vessels,also the degree of vascular invasion.Result：peripancreatic vessels invasion by pancreatic carcinoma were different due to location of tumor.The main peripancreatic vessels included： 5 cases in CA,4 cases in SA,6 caes in SMA,5 cases in PV,7 cases in SV,8 cases in SMV.The vessel invasion signs included encasement,infiltration and thrombosis,narrow or block cavity.Conclusion：64-detector CTA has important value in diagnosing pancreatic carcinoma and assessing its relationship to peripancreatic vessels and can provide basis of predicting operative respectability of tumor.
