| 摘 要： | 目的 探讨CT冠状动脉成像(CTCA)与冠状动脉导管造影(ICA)评估冠状动脉钙化狭窄程度的一致性。方法 选取接受CTCA和ICA、且图像无明显伪影的45例冠状动脉钙化狭窄患者;分别测量其病灶处钙化CT值、血管CT值,计算二者的CT比值,即血管钙化CT比值=病灶周围钙化最高CT值/病灶周围血管近端无钙化层面的血管CT值。以所用患者血管钙化CT比值的总平均值为分界值,将病例分为A、B两组。分别比较两组中CTCA与ICA诊断冠状动脉钙化狭窄程度的一致性。结果 45例患者血管钙化CT比值的总平均值为3.04±0.89;A组血管钙化CT比值<3.04,共21例,CTCA与ICA对其狭窄程度评估的吻合率为95.24%(20/21),诊断一致性极好(Kappa=0.82,P<0.05);B组血管钙化CT比值≥3.04,共24例,CTCA与ICA对其狭窄程度评估的吻合率为37.50%(9/24),诊断一致性差(Kappa=0.172,P<0.05)。结论 当血管钙化CT比值<3.04时,采用CTCA评估冠状动脉钙化狭窄程度,与ICA的评估结果具有较好的一致性。
