摘要(Abstract)：
目的探讨64层螺旋CT对冠状动脉粥样硬化病变的显示情况及临床价值。方法对69例临床诊断或疑诊冠心病的患者行64层螺旋CT冠状动脉成像检查及导管法冠状动脉造影。冠状动脉管腔内径减少>50%定义为显著狭窄。结果在69例患者冠状动脉的788节段(血管直径≥1.5mm)中,CT图像能够满足管腔评价者为778节段(98.7%),其中64层螺旋CT显示中度或中度以上狭窄(≥50%)的敏感性和特异性分别为81.9%和99.0%,阳性预测值和阴性预测值分别为95.9%和95.1%。如果在方法学上进行校正,敏感性将达91.8%。结论64层螺旋CT显示冠状动脉狭窄的准确性(95.2%)较高,在冠状动脉疾病的初步诊断以及介入治疗的筛选方面,是一种颇具潜力的无创性检查方法,但尚不能完全取代传统的导管法冠状动脉造影。
