Will an MRI rip out piercings?
MRI scanning of a patient with dermal piercings is not ideal as some dermal piercings can have magnetic components and so may feel a significant pull on the skin if allowed to enter the MR Environment. Dermal piercings may also cause distortions within the imaging field of view.
