| 目的 探讨320排容积CT心脏成像在小儿法洛四联症（TOF）诊断与治疗中的价值。方法 对20例临床拟诊为TOF的患儿行320排VCT检查，并将CT检查结果与同期超声检查结果对照。结果 20例患者中320排VCT确诊16例，US确诊18例；对16例320排VCT及US均诊断为TOF患儿的McGoon指数分别为1.13±0.04和1.01±0.04（t=1.521，P=0.149）；以手术为金标准，320排VCT及US对室间隔缺损检出率分别为80.00%（16/20）和90.00%（18/20，P>0.05）。320排VCT和US测量室间隔缺损最大径分别为（4.98±0.29）mm和（4.96±0.31）mm（t=0.258，P=0.800），测量的TOF患儿主动脉骑跨率分别为（0.27±0.01）%和（0.28±0.01）%（t=-0.019，P=0.250）。结论 320排VCT可清楚显示患儿TOF各种畸形，可较准确地评估TOF患儿肺动脉发育及大于2 mm的室间隔缺损，对术前治疗计划的制定有重要意义。 |

| Objective To explore the value of 320-row VCT cardiac imaging in the diagnosis and treatment of tetralogy of Fallot (TOF) in children. Methods Twenty children with suspected TOF underwent 320-row VCT cardiac imaging, and all of 320-row VCT diagnostic information were compared with those of ultrasonography (US). Results In all of the 20 patients, 320-row VCT cardiac imaging found 16 TOF children, US found 18 TOF children. McGoon index calculated by 320-row VCT and US were 1.13±0.04 and 1.01±0.04 (t=1.521, P=0.149). For the diagnosis of ventricular septal defect (VSD), taking operation result as the gold standard, the detection rates was 80.00% (16/20) in 320-row VCT and 90.00% (18/20) in US, respectively (P>0.05). The maximum diameter of VSD was (4.98±0.29)mm in 320-row VCT, and (4.96±0.31)mm in US (t=0.258, P=0.800). The aortic overriding rates in TOF patients measured by 320-row VCT and US were (0.27±0.01)% and (0.28±0.01)% respectively (t=-0.019, P=0.250). Conclusion 320-row VCT can clearly shows a variety of malformations of TOF in children, and accurately assesse the pulmonary development situation and the size of VSD above 2 mm, which is important for planning the preoperative treatment programs. |
