Role of positron emission tomography in etiological evaluation of patients with dementia / 国际脑血管病杂志

ABSTRACT

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.
