The aim of the study is to retrospectively evaluate brain perfusion and oxygenation in acute migraine attacks. Magnetic resonance perfusion and susceptibility weighted imaging are the technics to measure perfusion and oxygenation respectively.
The aim of the study is to demonstrate a possible correlation between areas of hypoperfusion and prominent cortical veins during migraine attacks. These focal ares of altered vascular supply of the brain will be evaluated for correlation with topograhy of symptoms.
