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.
