Headache Versus Non-headache Day Clinical Trial
Official title:
Functional MRI and MR Angiography Used in Spontaneous Migraine
The purpose of this study is to examine migraineurs during spontaneous migraine attacks
without aura, using high resolution magnetic resonance imaging (MRI), to study following:
- Changes in resting state blood-oxygenation-level-dependent-signal (BOLD-signal) using
functional MRI (fMRI).
- Changes in circumferences of intra- and extracranial arteries using MR-angiography
(MRA).
- Changes in regional and global cerebral blood flow (CBF) using the arterial spin
labeling (ASL) method.
Moreover to perform diffusion tensor imaging (DTI) scans during spontaneous migraine
attacks.
The migraine specific drug sumatriptan will be given to relieve pain and the effect will be
registered using MRA and fMRI if possible.
