摘要
先天性心脏病是胎儿期最常见的先天畸形。随着MRI新技术的出现,心脏MRI近年来已经逐渐用于胎儿先天性心脏病的产前评估。相位对比MRI、4D血流MRI、T1 mapping以及T2 mapping等心脏MRI新技术不仅可以对血管管径、血流流量、心室大小以及心室射血分数等进行量化分析,还可以对循环血氧饱和度与血细胞容量提供定量信息。就胎儿MRI的心电门控技术、心脏MRI新技术、心脏MRI对胎儿心血管系统量化评估及其发展前景进行综述。
Congenital heart disease is the most common congenital malformation in fetus.With the emergence of new MRI technologies,cardiac MRI has been gradually used in prenatal evaluation of fetal congenital heart disease in recent years.New cardiac MRI techniques such as phase contrast MRI,4D flow MRI,T1 mapping,and T2 mapping can not only be used to quantitatively analyze vascular diameter,blood flow,ventricular size,and ventricular ejection fraction,but also provide quantitative information on circulatory oxygen saturation and blood cell volume.We reviewed the fetal MRI ECG gating technology,new cardiac MRI techniques,cardiac MRI quantitative assessment of the fetal cardiovascular system and its development prospects.
