Moyamoya disease (MMD) is a chronic and progressive cerebrovascular stenosis or occlusive disease that occurs near Willis blood vessels. Diffusion tensor imaging (DTI) and functional magnetic resonance imaging (fMRI) are used to detect the microstructure of white matter and the function of gray matter, respectively. The damage of these structures will lead to the change of cognitive level in patients with moyamoya disease. In this paper, the principles of DTI and fMRI, their applications and challenges in moyamoya disease are reviewed.
烟雾病（MMD）是一种发生在 Willis 血管附近的慢性进行性脑血管狭窄或闭塞性疾病。弥散张量成像（DTI）和功能磁共振成像（fMRI）分别用于检测白质的微观结构和灰质的功能。这些结构的损伤将导致烟雾病患者认知水平的改变。本文综述了 DTI 和 fMRI 的原理、它们在烟雾病中的应用及挑战。
