电子束X线断层扫描(EBCT)在经静脉冠脉造影术中的应用,是近来兴起的一项非侵入性冠脉狭窄的检查手段。经肘前静脉以4ml/s的速度注射造影剂(Iopromide Schering)10ml,并连续拍摄20幅X线断层照片,显示造影剂通过主动脉的全过程。从造影剂注入到主动脉的最高强度显影的时间称为经过时
The application of electron beam tomography (EBCT) in transthoracic coronary angiography is a recently introduced noninvasive method of coronary artery stenosis. 10 ml of Iopromide Schering was injected through the antecubital vein at a rate of 4 ml / s, and 20 radiographs were taken continuously to show the whole process of the contrast medium passing through the aorta. The time from the injection of the contrast medium into the highest intensity of the aorta is called elapsed time
