在非白人人种中,颅内动脉粥样硬化疾病可能是最常见的缺血性卒中的病因。高分辨核磁成像的进展,使清晰显示大脑中动脉动脉管壁和斑块成分成为可能,并且高分辨核磁具有良好的观察者内和观察者间一致性。作为3D TOF MRA的补充,高分辨核磁能够弥补MRA的不足,从而能够发现MRA上无法发现的动脉粥样硬化斑块;颅内斑块的增强显像有可能用于识别斑块的易损性。在未来,对于高分辨核磁的影像表现和缺血事件发生的相关尚需要更多研究,它具有重要的临床意义。 Among non-white people, intracranial atherosclerotic disease may be the most common cause of ischemic stroke. Advances in high-resolution magnetic resonance imaging have made it possible to clearly show the arterial wall and plaque components of the middle cerebral artery, and high-resolution NMR has good interobserver and interobserver agreement. In addition to 3D TOF MRA, high-resolution nuclear magnetic resonance can compensate for the lack of MRA to detect atherosclerotic plaques that are undetectable on MRA; enhanced imaging of intracranial plaques may be used to identify plaque vulnerability . In the future, more research is needed on the correlation between high-resolution magnetic resonance imaging and the occurrence of ischemic events, which has important clinical significance.
