In this retrospective study, questionnaires and screening forms were analyzed to identify all subjects with implants and/or tattoos cleared for imaging at our passively shielded 7T whole-body MR system. Over the past 11 years, 496 out of 2370 healthy volunteers and volunteers with known pathologies had implants and/or tattoos and underwent a 7T MR examination. None of the subjects reported any discomfort related to heating or force during or after imaging. No findings regarding safety occurred and all examinations could be safely performed.
