| 摘 要： | 目的:比较64层螺旋CT(MSCT)和16层螺旋CT显示小肠单个出血点持续出血的敏感性.方法:取一透X线容器,盛入适量清水制成模型.采用微泵注射器分别模拟0.1、0.2、0.3、0.4和0.5 ml/min的出血速度通过3F微导管将3%的对比剂注入模型内,分别行64层螺旋CT和16层螺旋CT扫描.比较其出血检出的敏感性和差异性.结果:64层螺旋CT和16层螺旋CT均可显示0.1～0.5 ml/min的模拟出血,且随着出血量增加显示的更清楚.结论:64层螺旋CT和16层螺旋CT在显示小肠单个出血点持续出血的敏感性上差异无显著性意义.

| Abstract: | Objective:To compare the sensitivity of 64-MSCT vs 16-MSCT in detecting a single point of persistent intestinal hemorrhage.Methods:An experimental model made with a container containing appropriate amount of water was scanned by 64-MSCT and 16-MSCT respectively 30s after 3% contrast agent was injected at different rate of 0.1,0.2,0.3,0.4,and 0.5ml/min which imitated the status of bleeding intestine.The sensitivity and difference of 64-MSCT and 16-MSCT in detecting intestinal hemorrhage were compared.Results... |
