目的 探讨64 排螺旋CT冠状动脉成像(CTA)在冠状动脉狭窄诊断中的应用价值。 方法 选取2010年8月-2012 年8月间收治的90例临床诊断或疑似冠心病患者,所有患者均先实施64排螺旋CT冠状动脉CTA,然后所有患者实施常规冠状动脉造影,对比不同诊断方法的诊断结果,评估两种诊断方法对于冠状动脉狭窄的准确率及精确度。 结果 64 排螺旋CT冠状动脉CTA检出1处明显狭窄者36例,冠状动脉造影检出1处明显狭窄者36例,两组检查方法诊断冠状动脉狭窄对比,差异无统计学意义(P>0.05)。冠状动脉CTA诊断灵敏度为86.12%,特异度为94.21%,阳性预测值为80.33%,阴性预测值为97.11%,冠状动脉造影诊断灵敏度为72.19%,特异度为84.65%,阳性预测值为71.35%,阴性预测值为87.41%。冠状动脉CTA的诊断准确率高于冠状动脉造影,差异有统计学意义(P<0.05)。 结论 64 排螺旋CT冠状动脉CTA诊断冠状动脉狭窄的准确度及灵敏度都较高,对早期轻度狭窄诊断灵敏度优于传统动脉造影,对于辅助患者治疗具有重要作用,值得在临床推广应用。
