摘　　要：目的:研究多层螺旋CT多期扫描及影像表现在诊断胰腺癌的临床意义及进展。方法:34例经病理证实胰腺癌,团注法以3～4mL/s速度注入对比剂行动态三期增强扫描,时间分别是20s、40s、65s,层厚层距3～5mm,分析其影像改变,并分析和比较正常胰腺和肿瘤在三期扫描的增强情况,研究其诊断及可切除性评估准确性。结果:34例胰腺癌中胰头癌22例,胰体癌7例,胰尾癌2例,弥漫性分布3例。病灶大小2～11.5cm不等,肿瘤-胰腺对比在动脉期、胰腺期及门脉期分别为(23.25±11.31)、(63.58±26.34)、(43.15±22.53)。根据胰腺癌影像表现,34例中有30例被正确诊断,术前认为可切除14例。结论:多层螺旋CT多期扫描技术在胰腺癌的诊断和可切除性评估上具有重要临床价值。　Objective To study the clinical significance of multi-detector row helical CT and contrast-enhanced multiphasic imaging in diagnosing pancreatic carcinoma.Methods Thirty-four patients with proved pancreatic adenocarcinomas underwent multiphase,contrast-enhanced,multi-detector row CT.The arterical phase,pancrdatic parenchymal phase and portalvein phase began at 20 s,40 s and 65 s after the start of the injection at a rate of 4 mL/s.Thickness and pitch was 3～5 mm.The images were analyzed.The enhancement of normal pancreas and tumor were measured and compared during all three imaging phases.The diagnosis and resectabolity were evaluated.Results Among 34 patients,the tumors were in the head,neck and tail of pancreas in 22,7 and 2 cases respectively.Three were diffused.The diameter was from 2 to 11.5 cm.Tumor-pancreas contrast was significant in arterical phase（23.25±11.31）,in pancrdatic parenchymal phase（63.58±26.34）and in portalvein phase（43.15±22.53）.According to the image finding,30 of 34 cases were demonstrated accurately,14 cases were resectable before operation.Conclusion Multi-phase image of multi-detector row helical CT plays an important role in diagnosing and assessing the resectability of pancreatic tumor.
