Subjective acceptance of ultra-high-field MRI has not been evaluated in larger study groups yet. For this purpose, 573 volunteers underwent a 7T examination and were afterwards asked about sensations and side effects. Analysis revealed an overall high subjective acceptance of 7T examinations with mainly non-specific factors such as unpleasant room temperature, little contact to the staff or noise being criticized. Compared to 1.5T volunteers described considerably more often nausea or a metallic taste on 7T; however, the average degree of these effects was very low. Volunteers lying head first expressed more complaints than those lying feet first.
