| 目的 评价多层螺旋CT(MSCT)与冠状动脉造影对比,诊断冠状动脉中、重度狭窄(即管腔狭窄≥50%)的准确性和局限性。方法 选择在1个月内先后行64层螺旋CT和冠状动脉造影检查的28例患者(其中男19例,女9例,年龄39~78岁,平均63.6岁)入组,分析两种检查的诊断结果。结果 依节段计算MSCT的准确性,其灵敏度、特异度、阳性预测值和阴性预测值分别为46.5%、97.6%、86.8%和84.3%。若去除其中31个冠脉节段由于严重钙化而影响诊断的因素,则MSCT的诊断灵敏度、特异度、阳性预测值和阴性预测值分别为66.7%、98.6%、90.3%和93.6%。结论 MSCT冠状动脉成像是一种简便易行、安全可靠、风险小的无创性检查,对诊断冠心病尤其针对筛选冠心病而言有较好的前景,但也有一定局限性。 |

| Objective To compare the accuracy and limit of 64-slice spiral CT (MSCT) coronary angiography with invasive coronary angiography in the detection of significant coronary stenosis (≥50% lumen diameter narrowing). Methods Data were assessed from 28 subjects (19 men, 9 women) (mean age 63.6 years; range 39-78 years) referred to MSCT who also had undergone invasive coronary angiography within a time frame of one month. Images of MSCT and invasive coronary angiography were analyzed. Results The accuracy of coronary MSCT was computed on a per segment basis. Average sensitivity, specificity, positive predictive value, and negative predictive value of MSCT were 46.5%, 97.6%, 86.8% and 84.3%, respectively. If excluding the effect of 31 coronary segments with severe calcification, the sensitivity, specificity, positive and negative predictive values of MSCT were 66.7%, 98.6%, 90.3% and 93.6%, respectively. Conclusion MSCT coronary angiography is simple, reliable, noninvasive and low risk, it has a good potential for the detection of coronary stenosis, and may be most useful for excluding coronary artery disease. But it has its limits. |
