Multi-slice CT coronary angiography is a rapidly developing noninvasive diagnostic technique that can be used to detect coronary stenosis. Detection of coronary stenosis by coronary angiography is usually hindered by limited image quality, motion artefacts caused by heart contractions, and artefacts caused by extensive calcification. In addition, the radiation exposure is relatively great. Multi-slice CT coronary angiography, however, can reliably rule out coronary stenosis. At this time, multi-slice CT coronary angiography is not a routine part of the diagnosis of coronary artery disease. In the future, the target population for this technique may include asymptomatic high-risk patients and symptomatic low- or intermediate-risk patients for severe coronary artery disease.
多层螺旋CT冠状动脉造影是一种快速发展的无创诊断技术，可用于检测冠状动脉狭窄。冠状动脉造影检测冠状动脉狭窄通常受到图像质量有限、心脏收缩引起的运动伪影以及广泛钙化引起的伪影的阻碍。此外，辐射暴露相对较大。然而，多层螺旋CT冠状动脉造影可以可靠地排除冠状动脉狭窄。目前，多层螺旋CT冠状动脉造影并非冠心病诊断的常规组成部分。未来，这项技术的目标人群可能包括无症状高危患者以及有症状的重度冠心病低危或中危患者。
