多层螺旋CT"双低"扫描在冠状动脉成像中的临床应用OACSTPCD
Clinical Application of Coronary Imaging with "Double Low" Multi-Slice Spiral Computed Tomography Angiography
目的 探讨多层螺旋CT低辐射剂量及低对比剂用量在冠状动脉成像中的临床应用.方法 对疑诊冠心病并且确定检查的200例患者随机分成A组(n=100,对比剂用量为1.2 mL/kg)、B组(n=100,对比剂用量为0.8 mL/kg),两组患者再随机分为A1,B1,A2和B24个亚组.其中A1,B1采用回顾性心电图(Electrocardiography,ECG)门控技术,A2、B2采用前瞻性ECG触发技术,分别对其进行冠状动脉检查,计算不同组间对比剂…查看全部>>
Objective To investigate the clinical application value of multi-slice spiral Computed Tomography Angiography (CTA) with low radiation dose and low contrast-medium dose in coronary imaging. Methods To identify 200 patients with suspected coronary heart disease and after examination of patients were randomlLy divided into A group A (n=100, contrast-medium dose was agent for 1.2 mL/kg) and, B group B (n=100, contrast-medium dose was agent for 0.8 mL/kg), furth…查看全部>>
