Podcast #381: MRI... Burns?

Author: Sam Killian, MD

Educational Pearls:

• MRI machines can generate enough heat from the radiofrequency to cause thermal burns

• Patients with EKG stickers, medication patches, clothing impregnated with metallic ions, etc., can all increase risk of burns

• Even skin-to-skin contact within the patient can cause a misinterpretation from the software and increased energy, leading to burn
