PET is a versatile imaging technique that is advancing our understanding of cerebrovascular disease and intracerebral pathophysiology. In this Review, Evans and colleagues describe mechanistic insights from PET studies relating to the metabolic pathophysiology of carotid atherosclerosis, salvageable penumbra after stroke, and neuroinflammatory changes associated with small vessel disease and vascular cognitive impairment.
