摘　　要：双源CT已成为临床诊断冠心病的一线检查手段,但与侵入性冠脉造影(Invasive Coronary Angiography,ICA)相比,其诊断冠脉狭窄程度的敏感性和特异性仍有较大程度的波动。以侵入性冠脉造影为金标准,本文对常见的影响双源CT冠脉造影评估冠脉狭窄程度的因素作一综述。Since the advent of dual-source CT in 2005, dual-source CT coronary angiography （DSCT-CA）has been the first line examination method for the coronary artery disease （CAD）, with its high temporal resolution, spatial resolution and the characteristics of the noninvasive examination.But compared with the invasive coronary angiography, the sensitivity and specificity of dual-source CT coronary angiography in the diagnosis of coronary artery stenosis degree is still with a larger degree of volatility.With invasive coronary angiography as the gold standard, this review presents the common factors which influence the evaluation of the degree of coronary stenosis by dual-source CT coronary angiography.
