摘　　要：目的:探讨320排容积CT一站式成像技术在胰腺炎诊断中的优势及临床应用价值。方法:对46例胰腺炎患者注射造影剂后,利用东芝320排CT进行胰腺容积扫描。数据导入东芝体部灌注软件对全胰腺进行容积灌注分析,同时选择最佳时相重组平扫、增强各期图像,重组动脉CTA、静脉、门脉CTV及胰周引流管重建。结果:43例病例获取良好的平扫及多期增强容积图像、动态DSA图像、动脉CTA、门脉CTV以及全胰腺低剂量容积灌注图像。结论:320排容积CT胰腺炎一站式成像技术可以动态观察全胰腺平扫至增强各期血流灌注情况,同时对病灶本身、整个胰腺及邻近脏器灌注情况进行定性、定量分析,真正实现了一站式扫描,对胰腺炎病变具有极高的临床诊断价值。Objective To evaluate the clinical advantages and value of pancreatitis dynamic volume imaging by one-stop examination with 320 detector row CT. Methods After having injected the contrast medium, dynamic volume scanning was performed for all 46 patients with Toshiba 320 detector row CT by one-stop examination. The data were analyzed with Toshiba bocly perfusion software. Then the non-contrast and contrast axial thick layer images, CTA, vein and Portal vein CTV were recombined by selecting the data of the best time phase. Results Forty-three cases obtained good images of non-contrast and contrast, CTA, vein and portal vein CTV, and the whole pancreas perfusion. Conclusion Volume Imaging with 320 Detector Row CT by one-stop examination can observe the blood perfusion character of whole pancreas from non-contrast phase to contrast phase dynamically. The qualitative and quantitative analysis of the perfusion character can be performed for the whole lesions, organs and the adjacent organs.
