摘　　要：目的本研究比较了试验性增强法与常规增强法在肝脏CT动态增强扫描中的应用情况，探讨了试验性增强法在肝脏CT动态增强中的应用价值。方法对425倒接受肝脏CT动态增强扫描检查的患者进行回顾性分析。其中第一组203人次按常规方法行CT动态增强（在静脉开始注射造影剂后14～18s进行动脉期扫描），第二组222人次接受试验性增强法CT动态增强检查。比较、分析两组增强结果。结果第一组57．1％（116／203）的病例获得了最佳的肝动脉期图像，第二组87．4％（194／222）的病例获得了最佳的肝动脉期图像。统计学分析两组肝动脉期图像质量优良率的差异具有统计学意义。结论试验性增强法肝脏CT动态增强扫描对于肝脏动脉期的显示优于常规CT动态增强检查法。Objective The purpose of this study was to identify the usefulness of the test - injection method as compared with the fixed - time method in dynamic CT of liver. Methods 425 patients have been studied that underwent dynamic CT. 203 patients （group 1 ） accepted the fixed -time method （14 -18 seeond scan time delay in the hepatic arterial phase [ HAP] ）. 222 patients （ group 2） accepted the test - injection method. The adequacy of the HAP was evaluated. Result In group 1, 57.1% （ 116/ 203 ）of the cases were obtained at the optimal HAP; the percentage in group 2 was 87.4% （194/222）of the eases. This difference was statistically significant （p 〈 0. 05 ）. Conclusion The CT using the test - injection method resulted in better optimal HAP than the CT using the fixed - time method.
