We explored the clinical value of low-tube voltage prospective second-generation ECG-triggered 320-row CT angiography in infants with complex CHD (37 male, 23 female, aged 0-2 years). The diagnostic accuracy of 320-row CT in complex CHD was 99.4% for intracardiac cardiovascular malformations, 99.8% for extracardiac cardiovascular malformations, and 100% for other malformations. The average subjective overall image quality score for cardiac structures was 3.7 ± 0.5 points. Second-generation 320-row CT angiography with low-tube voltage and prospective ECG-triggered volume target scanning allows accurate diagnosis of cardiovascular anomalies in infants with complex CHD.
我们探讨了低管电压前瞻性第二代心电图触发的320排CT血管造影在患有复杂先天性心脏病（CHD）婴儿（37例男性，23例女性，年龄0至2岁）中的临床价值。320排CT对复杂CHD中心内心血管畸形的诊断准确率为99.4%，心外心血管畸形的诊断准确率为99.8%，其他畸形的诊断准确率为100%。心脏结构的平均主观整体图像质量评分为3.7±0.5分。低管电压和前瞻性心电图触发容积靶向扫描的第二代320排CT血管造影能够准确诊断患有复杂CHD婴儿的心血管异常。
