摘　　要：症状性颅内动脉粥样硬化性狭窄的科学评估影响临床与科研的方方面面,如危险分层、临床决策及研究分组等。除传统的形态学评估外,随着精准医学的兴起,使用磁共振方法进行个体化血流评估领域出现了许多新的技术,涉及组织灌注评估、侧支循环评估及狭窄部位血流动力学评估等不同方面。这些新技术的出现提高了症状性颅内动脉粥样硬化性狭窄诊断与治疗的个体化水平,也为未来的研究与临床应用提供了新的思路。The scientific assessment of symptomatic intracranial atherosclerotic stenosis（ICAS） affects all aspects of clinical work and scientifi c research, such as risk stratifi cation, clinical decision making and study group assignment, etc. In addition to the traditional morphological evaluation, with the emergence of precision medicine, many new techniques of MRI came in to practice, using magnetic resonance imaging for individualized assessment of blood flow, involving perfusion, collateral circulation and hemodynamics, etc. The emergence of these new techniques improves the individualized diagnosis and treatment of ICAS, and also provides a new train of thought for the clinical application and future research.
