The primary outcome was the mean change in pain score from baseline (before any study procedure) to the highest reported pain level during MRI with a CI magnet in place. Secondary outcomes included patient\u2010reported survey responses regarding their MRI experience and the interpretability of the brain MRI scans involving rotating magnets, as assessed by two independent, blinded neuroradiologists.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Twenty\u2010three MRI scans (21 patients) with CIs were analyzed. Eleven scans (47.8%) involved implants containing internal magnets designed to self\u2010align with the magnetic field. The mean pain\u2010score difference unrelated to headwrap use was significantly lower for rotating magnet devices than fixed magnets (0.7 vs 4.0,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u2009.02). No magnet displacement or depolarization occurred. In six MRI brain sequences, the mean maximal signal\u2010loss artifact measured 6.1\u2009cm (SD 1.2\u2009cm) on axial images for rotating magnet devices. When assessing if the MRI could answer the question for which the scan was ordered, 100% of responses (n\u2009=\u200912) ranged from slightly agree to strongly agree. The majority of patients (70.0%) indicated they would undergo another MRI if medically necessary.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>CIs containing rotatable magnets reduce MRI\u2010related pain compared to those with fixed magnets.
