[Abstract] Vascular cognitive impairment (VCI) is a group of syndromes ranging from mild cognitive impairment to dementia. As a functional magnetic resonance imaging (fMRI) technique, arterial spin labeling (ASL) can mark the cerebral blood of VCI patients at various stages without relying on the blood-brain barrier by marking the hydrogen protons in arterial blood with specific pulses. Flow rate with good time resolution has become an important imaging tool for diagnosis and follow-up of VCI. This paper reviews the basic principles of ASL technology and the research progress in VCI in recent years.
