Background Patient characteristics, higher device cost, and vendor contracts likely prevent use of magnetic resonance imaging (MRI)‐conditional pacemakers (MRC) in all pacemaker (PM)‐eligible patients. We sought to identify the incidence and predictors of MRI scan utilization in MRC recipients. Methods Patients receiving an MRC or non‐MRI‐conditional PM (NMRC) at four centers were included. Incidence of MRI scans following PM insertion was obtained from hospital records and patient phone calls. Results Of 1,244 patients (74 ± 12 years, 54.6% male), 927 had MRC and 317 had NMRC. At baseline, MRC recipients had a higher incidence of atrial tachycardia and MRI risk factors (syncope, recurrent falls, neurological disease, severe musculoskeletal disease, malignancy). In the MRC group, more patients had commercial health insurance (26% vs 15%, P
