摘要
目的探讨低剂量造影剂主动脉增强效果,以减少造影剂用量,从而减少造影剂肾病的发生。方法按体重70kg界限,交替进入正常剂量组和低剂量组,分别给予造影剂80ml和40ml,给药速度5ml/s,主动脉进行MIP,VR,CPR重建,评价血管的图像质量。结果正常剂量和低剂量造影剂主动脉成像图像质量没有统计学差异。结论40ml造影剂进行主动脉成像,可以获得满足临床需要的图像质量。
Objective To study the effect of low dose contrast media on enhancement of aorta,for decreasing the dose of contrast media,and then decreasing radiographic contrast nephropathy.Methods According to the threshold of 70kg body weight in turn to admission groups of common dosage and low dosage,group of common dosage was injected 80ml contrast media with speed of 5ml/s,group of low dosage was injected 40ml contrast media with same speed.Evaluating the image quality of the aorta reconstructing image with method of MIP,VR and CPR.Results The difference of the image quality between group of common dosage and group of low dosage was not significant.Conclusion The image quality of aorta can satisfy clinic by injecting 40ml contrast media.
