Interictal Hyperperfusion in the Higher Visual Cortex in Patients With Episodic Migraine

Abstract

Migraine pathophysiology is complex and probably involves cortical and subcortical alterations. Structural and functional brain imaging studies indicate alterations in the higher order visual cortex in patients with migraine. Arterial spin labeling magnetic resonance imaging (ASL‐MRI) is a non‐invasive imaging method for assessing changes in cerebral blood flow (CBF) in vivo.
