| 摘 要： | 传统的心脏磁共振检查需借助外源性对比剂才能评价心肌血供和代谢。血氧水平依赖磁共振成像技术(blood oxygen level dependent magnetic resonance,BOLD-MR)可不依赖对比剂,通过检测组织中脱氧血红蛋白水平高低即可反映局部血氧代谢情况。作为一种无创的功能磁共振成像技术,它在解释氧代谢相关病理生理过程中显示出较大的应用前景,笔者旨在介绍近年来BOLD-MR在心血管疾病中的应用进展。

| Abstract: | Traditional cardiac magnetic resonance imaging depends on exogenous contrast agents to evaluate myocardial blood supply and metabolism.Blood oxygen level dependent magnetic resonance is able to assess myocardial oxygenation by detecting the changes of deoxyhemoglobin,without the need of contrast agent.As a noninvasive functional imaging technology,it is promising in explaining the pathophysiological processes related to oxygen metabolism.This article aims to review the clinical application of this novel method in cardiovascular diseases in recent years. |
