摘要
目的评价64排螺旋CT用于诊断冠状动脉病变的临床价值。方法连续入选66名冠心病患者,均行64排螺旋CT冠脉三维成像和冠状动脉造影,以冠状动脉造影的结果为"金标准",计算64排螺旋CT诊断冠状动脉病变的敏感性,特异性,假阳性率,假阴性率,阳性预测值,阴性预测值。结果对照冠状动脉造影,64排螺旋CT诊断冠脉病变的敏感性为93.02%,特异性为98.21%,假阳性率为1.79%,假阴性率为6.98%,阳性预测值为97.56%,阴性预测值为94.83%。结论64排螺旋CT对于诊断冠脉病变有较好的敏感性与特异性,可用于冠心病患者的筛查。但目前的技术水平和各项技术指标仍有待提高,还无法替代传统的血管造影。
Objective To evaluate the value of in diagnosing coronary heart diease. Methods 66 consecutive patients diagnosed coronary heart diease have been examined by computed,tomography angiography and conventional coronary angi- ography. Based invasive coronary angiography, the sensitivity, specificity, false positive rate, false negative rate, positive pre- dictive value and negative predictive value of 64 detector - row computed tomography in diagnosing coronary heart diease were calculated. Results Based coronary angiography, the sensitivity, specificity, false positive rate, false negative rate, positive predictive value, negative predictive value of 64 detector - row CT in diagnosing coronary heart diease were 93.02%, 98.21%, 1.79%, 6. 98%, 97.56%, 94.83% respectively, Conclusion 64 detector - row computed tomography has relatively high sensitivity and specificity in diagnosing coronary heart diease. However, it couldn＇t replace the conventional invasive coronary angiography now.
