摘　　要：目的：探讨多层螺旋CT（multislice spiral computed tomography，MSCT）在腹腔干分支成像中的价值。方法：随机选取80例患者，均进行CT三期扫描。平扫后设置阈值方法，以腹腔干为靶血管、测量峰值时间，峰值时间加2s为最佳延迟时间。由两位CT医师共同采用最大密度投影（maximum intensity projection，MIP）、容积成像（volume rendering，VR）等方式进行影像后处理。结果：注射对比剂后24～28s进行扫描，是最佳的延迟时间，随机选择的80例受检者中腹腔干分支正常46例、变异16例、病变18例。结论：多层螺旋CT后处理技术能够清晰地显示腹腔干分支，为外科手术及介入治疗提供了一个重要的参考依据。Objective：To discuss the value of multislice spiral compute tomngraphy（MSCT） in imaging the branch of celiac think. Methods：MSCT examination was performed in 80 cases chosen at random. Celiac tnmk was chosen as target vessel, the peak-time plus 2 seconds as the best delay scanning time. All data were post-processed with maximum intensity projection （MIP） and volume rendering （VR） by two CT doctors. Results：The best delay scanning time was 24 - 28 s. There were 46 cases with normal celiac artery, 16 cases with variant celiac artery, and 18 cases with pathological celiac artery in 80 random-selected cases. Condusion：3D-CT imaging can show branch of celiac trunk clearly, which provides reference for surgery and intervention.
