From: Arterial spin-labeled MRI study of migraine attacks treated with rizatriptan
a Normalized ASL images during migraine attack show significant relative hypoperfusion in bilateral thalamic areas including hypothalamus, posterior cingulate, and cerebellum, and significant relative hyperperfusion in the frontal convexity as compared to the migraine-free state. b Normalized ASL images acquired 30 min after rizatriptan administration demonstrated recovered significant relative perfusion in the hypothalamus and its surrounding areas as compared to during migraine attack. a, b Two-tail view. Color bar is Z-score (SD)
