摘　　要：目的:探讨在CT增强检查中国人的造影剂用量。方法:将200例腹部增强检查的病人分为甲(100 mL)、乙(70 mL)两组,用相同的注射速率和扫描方法进行检查,观察两组病人主动脉期主动脉的CT值和肝实质期肝脏增强前后的的密度差值。结果:甲组主动脉的CT值均在100Hu以上,肝实质的密度差值均在20Hu以上,增强效果良好;乙组主动脉CT值在100Hu以下和肝实质期的密度差值在20Hu以下的均为1例。两组间无明显统计学差异(P>0.05)。结论:国人用70 mL。的造影剂也能获得良好的增强效果。Objective To evaluate the dose of contrast media used in enhanced CT in Chinese. Methods 200 patients in contrast-enhanced CT on abdomen were divided into two groups A (100 mL), B (70 mL), carry out the examination by using the same injection speed and scanning method , observing the CT value of main artery in main arterial phase and the hepatic dense difference between enhanced CT and unenhanced CT in hepatic phase. Results In group A,the CT value of main artery is all above 100 Hu and the hepatic dense difference is all above 20 Hu.the effect of enhanced CT is well; In group. B, there is only one case in both the CT value of main artery below 100 Hu and the hepatic dense difference below 20 Hu, respectively. There is no obvious difference on statistics between two groups (P>0. 05). Conclusion 70 mL of contrast media used in Chinese can also obtain fine effects.
