摘要:
 【摘要】 目的 探讨320排动态容积CT冠状动脉成像（CTA）诊断冠心病的准确性。 方法 2010年3月至2010年9月对临床拟诊为冠心病的82例患者先后行冠状动脉CTA及冠状动脉造影（ICA）检查，并以ICA为金标准，评估320排CTA诊断冠状动脉狭窄≥ 50%及≥ 70%的敏感度、特异度、阳性预测值及阴性预测值。 结果 CTA成像质量4分71例（86.6％），平均心率为67次/min；3分10例（12.2％），平均心率为74次/min；2分1例（1.2％），心率为83次/min；1分0例，全部病例均无阶梯伪影。CTA发现174个狭窄≥ 50%的节段，ICA发现144个。以ICA为金标准，320排CTA诊断狭窄≥50%的敏感度、特异度、阳性预测值及阴性预测值分别为93.1%、96.0%、77.0%和99.0%。CTA发现40个狭窄≥ 70%的节段，ICA发现40个。以ICA为金标准，320排CTA诊断狭窄≥ 70%的敏感度、特异度、阳性预测值及阴性预测值分别为100%、95.6%、45.5%和100%。 结论 320排CTA图像质量好，诊断冠心病准确可靠。
