功能磁共振成像(functional magnetic reso-nance imaging,f MRI)是一种用于研究认知功能的影像学方法,正越来越多地应用于临床。它既可以用于研究健康儿童大脑发育,也可用于儿童神经和精神疾病的研究,如癫痫、注意缺陷多动障碍、孤独症谱系障碍等。f MRI已开展约15年,以往较多应用于成人脑功能的研究,直到最近才开始应用于小儿神经病学的研究。目前颅脑CT、颅 Functional magnetic resonance imaging (fMRI) is an imaging method used to study cognitive function and is increasingly being used clinically. It can be used to study healthy children’s brain development, can also be used for children’s neurological and mental illness research, such as epilepsy, attention deficit hyperactivity disorder, autism spectrum disorders. F MRI has been around for about 15 years and has been used more often in studies of adult brain function until recently in pediatric neurology. At present, brain CT, cranial
