摘要：

摘要目的探讨西门子双源CÞ冠状动脉成像对不同狭窄程度冠状动脉的诊断价值。方法对¹00例疑诊为冠心病（CHÐ）患者分别进行双源CÞ冠状动脉成像（ÐSCÞCA）和冠状动脉造影（CAG）检查，对ÐSCÞCA检查图像质量进行Frânk评分，计算ÐSCÞCA对不同狭窄程度冠状动脉的敏感性、特异性、阳性预测值、阴性预测值和准确率，评价ÐSCÞCA和CAG对冠状动脉狭窄的一致性。结果¹00例患者均顺利完成ÐSCÞCA和CAG检查，CAG共采集可评价血管¹³5¹段，ÐSCÞCA均可评估。¹00例患者ÐSCÞCA图像质量均可用于诊断，其中4分79例，³分¹7例，²分4例，¹分0例；ÐSCÞCA评价冠状动脉轻度狭窄的敏感性、特异性、阳性预测值、阴性预测值和准确率分别为85.9%、97.8%、90.6%、98.¹%和96.³%，中度狭窄的敏感性、特异性、阳性预测值、阴性预测值和准确率分别为9³.6%、99.8%、99.¹%、98.5%和98.5%，重度狭窄的敏感性、特异性、阳性预测值、阴性预测值及准确率分别为9².7%、¹00%、¹00%、99.²%和99.³%；ÐSCÞCA与CAG评估冠状动脉一致性良好K=0.86²（＞0.75）。结论西门子双源CÞ冠状动脉成像可清晰描述冠状动脉系统的情况，对冠状动脉狭窄的诊断具有较高的准确率。
