Physicians Pre-Conference: Basics of MRI-MRI Safety: Biology vs. Physics

Video Transcription

Video Summary

The speaker reviews MRI safety, focusing on adverse event epidemiology, MR environment hazards, prevention, and emergency response. FDA data showed 1,548 reported adverse events over 10 years, mostly thermal injuries, then mechanical and projectile events, with 10 deaths. The talk explains risks from the static magnetic field, gradient fields, and radiofrequency energy, including projectile forces, peripheral nerve stimulation, heating, noise, and device malfunction. Prevention strategies include proper facility design, screening, equipment labeling, patient monitoring, and reducing conductive materials. Emergency guidance covers cardiac/respiratory events, safe patient removal, and when magnet quenching is appropriate.
