Basal dilation
Perivascular spaces are gaps containing interstitial fluid that span between blood vessels and their host organ, such as the brain, which they penetrate and serve as extravascular channels through which solutes can pass. Like the blood vessels around which they form, perivascular spaces are found in both the brain subarachnoid space and the subpial space. Perivascular spaces surrounding arteries in the cerebral cortex and the basal ganglia are separate… 웹2024년 3월 26일 · Methods— This study comprised 1237 participants (aged 57.2±9.4 years, 37.6% men) who underwent brain magnetic resonance imaging and magnetic resonance angiography.
