【摘要】 目的 评价多排螺旋CT(MSCT)冠状动脉钙化积分的临床价值。方法 50例患者(30例临床确诊冠心病，20例正常对照)行多排螺旋CT(MSCT)冠状动脉钙化积分检查，阈值选择为90Hu。结果 冠心病组的平均钙化分值为300.1±43.5，与无症状组的136.1±22.5比较，差异有显著性;以积分>300为阳性，灵敏度66.6%，特异度75%;以积分>400为阳性，灵敏度50%，特异度90%;以积分>500为阳性，灵敏度33.3%，特异度95%。结论 冠状动脉钙化积分作为心脏冠心病危险因素评价的一部分，有一定的临床价值，但必须与其他因素相结合进行综合分析。

    【Abstract】 Objective To evaluate the clinial value of multi-slice spiralCT(MSCT)scan in estimating the quantification of coronary artery calcification.Methods ECG gated MSCT was performed in50patients，of which30had coronary heart disease and20were asymptomic.Results Significant difference(P<0.05)in the mean coronary artery calcification score existed between coronary heart disease group(300.1±43.5)and asymptomic group(136.1±22.5).Taking>300as positive ......
