摘　　要：目的:探讨64排螺旋CT(64-MSCT)在冠心病诊断中的应用价值。方法:75例患者同时行64-MSCT冠状动脉成像检查和传统冠状动脉造影(CCA)。以CCA结果为金标准,观察64-MSCT对冠状动脉狭窄率≥50%病变的诊断价值。结果:75例患者中,651段血管的图像质量可用于临床诊断,64-MSCT诊断冠状动脉血管狭窄≥50%的灵敏度、特异度、阳性预测值、阴性预测值和准确度分别为87%、99%、92%、98%和98%。结论:64-MSCT可较好地诊断冠状动脉狭窄≥50%的病变,同时具有无创和简便的特点,可以作为临床冠心病筛查的重要方法。Objective：To evaluate the value of 64-slice spiral CT（64-MSCT） on diagnosis of coronary artery disease.Methods：Seventy-five patients underwent 64-MSCT coronary angiography and conventional coronary angiography（CCA） simultaneously.The diagnostic accuracy of MSCT to detect significant lesions（≥50%）was evaluated according to quantitative CCA.Results：Six hundred fifty-one vessels had diagnostic image quality in 75 patients.Sensitivity,specificity,positive predictive values,negative predictive values and accuracy of the vessels were 87%,99%,92%,98%and 98%,respectively.Conclusions：64-MSCT coronary angiography has an important role in diagnosing coronary artery stenosis higher than 50% and it is also non-invasive and simple,which can be considered as a valuable and important technique for excluding coronary artery disease.
