Evaluation of cerebrovascular reactivity in moyamoya disease using oxygen-dependent magnetic resonance imaging

iScience
Summary: Moyamoya disease (MMD) is a rare cerebrovascular disorder marked by progressive stenosis of the internal carotid arteries. Assessing cerebral hemodynamics, specifically cerebrovascular reactivity (CVR), is vital for MMD management and prognosis.
