BOLD-fMRI技术在心肌缺血中的研究进展

血氧水平依赖功能MRI成像(BOLD-f MRI)技术已经成为心肌无创检查的重要方法之一。已有研究证实其评估心肌缺血具有较高的准确性和可靠性。随着MRI设备的发展及扫描序列的优化,BOLD-f MRI技术不仅实现了对心肌缺血的定量评估,而且可以对存活心肌进行无创检出。

Advances of blood oxygen level-dependent functional MRI assessing myocardial ischemia

BOLD-fMRI has been an important approach of evaluating the status of myocardial ischemia noninvasively. The accuracy and reliability of evaluating myocardial ischemia using BOLD-fMRI have also been certified by previous studies. As the development of MR devices and sequences, BOLD-fMRI not only had the ability to diagnose the ischemia of myocardium quanlificationally, but also could detect viable myocardium noninvasively.
