摘　　要：高分辨率磁共振成像(HRMRI)是一项安全、无创、经济和可重复的检查方法,可以精确反映动脉粥样硬化的程度,对未来的临床事件有较高的预测价值。其核磁扫描像素可达到亚毫米级,采用"黑血"技术,广泛应用于动脉管壁及斑块成分的研究。应用HRMRI评估脑动脉粥样硬化斑块的易损性,包括动脉重塑、斑块负荷、斑块内出血和强化、斑块分布等特点,具有重要的临床意义。High-resolution magnetic resonance imaging （HRMRI） is a safe, non-invasive, inexpensive, accurate and reproducible clinical imaging modality, and the results can acutely reflect the extent of atherosclerotic disease and have high predictive values for future clinical events. It uses black blood imaging techniques and can obtain sufficient sensitivity for submillimetre imaging. HRMRI has been used widely to visualize the vessel wall and differentiate the components of atherosclerotic plaques. It is of important clinical meaning to evaluate plaque vulnerability with HRMRI, which is related to the remodeling pattern, plaque burden, intraplaque hemorrhage and contrast enhancement, and plaque distribution, etc.
