摘　　要：目的探讨新双源CT前瞻性心电门控序列扫描冠状动脉成像(MSCTA)对隐匿性冠心病的诊断价值。方法对80例无明显症状的冠心病患者行MSCTA检查后,其中32例于两周内行冠状动脉造影(CAG)检查,对其表现与常规心电图、动态心电图和CAG结果进行对照分析。结果 MSCTA与CAG有较好的一致性,MSCTA对隐匿性冠心病诊断准确率与常规心电图及动态心电图有统计学意义(P <0. 01),其准确率为93. 1%,敏感性为91. 8%,特异性为93. 9%,阳性预测值为90. 3%,阴性预测值为94. 9%。结论新双源CT前瞻性心电门控序列扫描冠状动脉成像可为隐匿性冠心病的早发现和早治疗提供一种无创性、快速便捷的影像检查方法。Objective To evaluate prospective cardio sequence scanning technology for dual-source CT in latent coronary heart disease（LCHD）. Methods 80 patients with LCHD underwent dual-source CT coronary angiography and conventional coronary angiography in 2 weeks successively. The findings of MSCTA,CAG,ECG,and DCG were analyzed. Results MSCTA had a good consistency with CAG in the diagnosis of latent coronary heart disease. There was significant difference（P〈0. 01） between MSCTA and ECG or DCG in the accuracy rate. The accuracy rate,sensitivity,specificity,positive predictive value and negative predictive value were 93. 1%,91. 8%,93. 9%,90. 3%,and 94. 9%,respectively. Conclusion Prospective cardio sequence scanning technology for dual-source CT may offer a non-invasive and fast way in the early diagnosis and early therapy of LCHD.
