摘要(Abstract):
目的探讨64层CT冠状动脉造影对冠状动脉的可诊断率及诊断冠心病的价值。方法选择连续行64层CT冠状动脉造影的可疑冠心病患者80例,患者同期行冠状动脉造影检查,评价CT冠脉造影对冠心病的诊断价值。结果以患者为评价标准,64层CT的可诊断率为98.75%;以冠状动脉主要分支为评价标准,可诊断率为96.88%;以冠状动脉节段为评价标准,可诊断率为97.25%。基于患者64层螺旋CT冠状动脉造影诊断冠心病的敏感性为97.92%,特异性为90.32%,阴性预测值为96.55%,阳性预测值为94.00%;基于冠状动脉主要分支的敏感性为92.13%,特异性为95.93%,阴性预测值为96.80%,阳性预测值为90.11%;基于冠状动脉节段的敏感性为90.74%,特异性为98.87%,阴性预测值为99.05%,阳性预测值为89.09%。结论 MSCT冠状动脉造影可以可靠地评价冠状动脉狭窄,能够作为筛查冠心病的无创性检查方法。
