摘要 目的:以选择性冠状动脉造影(SCA)为参考标准探讨128层SCT冠脉CTA评估冠状动脉狭窄程度的准确性及其价值。方法:回顾性分析36例疑似冠心病患者在1周内行128层SCT冠状动脉成像及SCA资料,对比分析128层SCT诊断冠状动脉轻、中、重度狭窄的敏感性、特异性、准确性、阳性预测值、阴性预测值。结果:36例患者经128层SCT冠状动脉成像后,共显示可评估的冠状动脉节段431个,评估率为90.5%(431/476),128层SCT诊断冠状动脉轻、中、重度狭窄的敏感性为61.1%、87.5%、78.1%,特异性为89.6%、98.7%、98.2%,准确性为87.2%、97.9%、96.3%,阳性预测值为34.9%、84.8%、82.1%,阴性预测值为96.2%、98.9%、97.7%。结论:128层SCT对评估冠状动脉狭窄有较高的准确性,可作为诊断冠状动脉病变的常规检查方法。
