These figures represent the percentage of recipients in the study who experienced discomfort, pain, or other complications during 1.5 T MRI (two 3.0 T scans were excluded from the figure). Kim et al. (2015) is a retrospective study looking at 1.5 T and 3.0 T MRI scans performed on CI recipients between 2003 and 2014. The study included 18 individuals; 5 recipients had Advanced Bionics devices, 11 had Cochlear devices, and 3 had MED-EL implants. Advanced Bionics recipients had 9 total 1.5 T scans; Cochlear recipients had 12 total 1.5 T scans and 2 total 3.0 T scans; and MED-EL recipients had 8 total 1.5 T scans.
