摘　　要：痴呆是一种以获得性认知损害为主的综合征, 主要表现为理解力、定向力、视空间能力等认知功能下降。由于不同类型痴呆的干预方法不同, 故鉴别诊断极为重要。正电子发射体层成像(positron emission tomography, PET)可通过不同示踪剂多角度反映脑功能变化, 为痴呆的鉴别诊断提供影像学依据。文章对不同类型痴呆患者的PET特点进行了综述, 以期为不同类型痴呆患者的鉴别诊断提供思路。Dementia is a syndrome mainly characterized by acquired cognitive impairment,which is mainly manifested by the decrease of cognitive functions such as understanding,orientation,and visuospatial ability.Due to different intervention methods for different types of dementia,differential diagnosis is extremely important.Positron emission tomography(PET)can reflect the changes of brain function from multiple angles through different tracers,providing imaging basis for the differential diagnosis of dementia.This article reviews the characteristics of PET in patients with different types of dementia in order to provide ideas for the differential diagnosis of patients with different types of dementia.
