I have a migraine disorder in which I can get prolonged aura. I often get regular head MRI and MRA as the blood vessels constrict. Anyway In the less powerful older MRI machines I dont feel anything. However the newer MRI machines with higher field strengths definitely make the top of my head feel like it is rippling which it probably is. I used to think it was the extra cooling fans that run over you during the scan. I thought the blasts of cold air were simply triggering fasciculation, but I think it is more of an effect of the strength. I feel I fasciculate all over in the 4T scanner and totally out of it afterwards. In comparison the normal lower strenth MRI scans don't have the same effect.
