中文摘要: |
先天性心脏病是最常见的先天性畸形,MRI在评价其术后心脏功能中具有重要作用。新技术四维血流分析(4D flow)可同时基于3个互相垂直的维度编码获得相位流速编码电影、多参数分析血流向量和峰值流速,并能可视化分析心内及心外结构的血流。本文对4D flow原理及其在儿童先天性心脏病中的应用进展进行综述。 |
英文摘要: |
Congenital heart disease (CHD) is the most common congenital malformation. MRI plays an important role in evaluating postoperative cardiac function of CHD. The new technology of 4D flow can be used to encode phase flow coded cine based on 3 vertical dimensions at the same time. Meanwhile, 4D flow can perform multi-parameter functional assessments of blood flow vector and peak flow velocity, also can visualize the structure and blood flow of the inner heart and the outer heart. The principle of 4D flow and its application in children with CHD were reviewed in this article. |
