: To determine whether gadolinium-enhanced three-dimensional magnetic resonance angiography can provide a noninvasive alternative to diagnostic catheterization for evaluation of pulmonary artery anatomy in tetralogy of Fallot.
Thirty-five consecutive patients with tetralogy of Fallot, who attended the cardiology outpatient department between January 2008 and December 2009, were included in the study. There were 21 males and 14 females, with a mean age of 9 ± 4.15 years (range, 3-21 years). Thirty-two patients had tetralogy of Fallot with varying severities of valvular and infundibular stenosis. Three patients had tetralogy of Fallot with pulmonary atresia. All patients underwent both cardiac catheterization with X-ray angiography and 3-dimensional magnetic resonance angiography within one month.
Measurements of right and left pulmonary arteries and aortopulmonary collaterals were equal by both methods. There was a good correlation between magnetic resonance angiography and catheterization measurements of branch pulmonary arteries.
Gadolinium-enhanced three-dimensional magnetic resonance angiography can be used as a reliable noninvasive alternative to X-ray cineangiography for delineation of pulmonary arterial anatomy in sick infants and young children, obviating the need for catheterization.
确定钆增强三维磁共振血管造影术能否为法洛四联症患者肺动脉解剖结构评估提供一种替代诊断性心导管检查的非侵入性方法。
本研究纳入了2008年1月至2009年12月期间在心脏病门诊就诊的35例连续的法洛四联症患者。其中男性21例，女性14例，平均年龄9 ± 4.15岁（范围3 - 21岁）。32例患者患有不同严重程度瓣膜和漏斗部狭窄的法洛四联症。3例患者患有肺动脉闭锁的法洛四联症。所有患者在1个月内均接受了X线血管造影的心导管检查和三维磁共振血管造影检查。
两种方法测得的左右肺动脉及主肺动脉侧支血管情况相同。磁共振血管造影与心导管检查对肺段动脉的测量结果具有良好的相关性。
钆增强三维磁共振血管造影术可作为一种可靠的非侵入性方法替代X线电影血管造影术来描绘患病婴幼儿的肺动脉解剖结构，从而无需进行心导管检查。
