Current FDA guidelines classify MR devices operating at up to 8 Tesla as insignificant risk. Vital sign and cognitive performance data supporting the safety of performing non-proton MR imaging of the human brain at 9.4 Tesla in healthy and for-cause volunteers are presented. These data add to the growing body of results that suggest ultra-high field MR imaging can be safely performed up to 9.4 Tesla.
