ABSTRACT Unexpected RF noise artifact “followed” a patient with an implanted spinal cord stimulator to multiple MR systems. Subsequent testing and clinical scanning showed no artifact, implying that the artifact originated from the implanted device. MR exams ( n = 173) performed over a two‐year period in patients ( n = 122) who had implanted spinal cord stimulators from the same manufacturer were reviewed for artifacts and device models. RF noise artifacts were observed in ~50% of exams in patients with a specific model of spinal cord stimulator, but only ~1%–8% of exams in other models from the same manufacturer. We hope that by describing this artifact, health care professionals can avoid service costs and scheduling delays.
