Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (MRI) uses magnets, and sub-atomic structures in the body, to look at the soft tissues and organs that X-rays don’t see. Use this section of the guide to learn how MRI works and what to expect during an MRI.

Dulcinea's Insight

  • Because magnetic energy is involved, it’s essential to tell your doctor and the MRI technician if you have any metallic implants, such as a pacemaker, or shrapnel in your body. Without informing them, an MRI could be seriously harmful.
