Magnetic resonance imaging (MRI) is sophisticated diagnostic equipment used to diagnose an array of health problems or conditions, including:
MRIs use no radiation like conventional X-rays or CT scans. They employ large magnet and radio waves to produce three-dimensional images. MRIs are very good at portraying soft tissues and bones in your feet and ankles.
People who have the following may not be good candidates for an MRI:
- Artificial heart valves
- Electronic inner ear implants
- Electronic stimulators
- Heart pacemakers
- Implanted pumps
- Metal fragments in the eyes
- Surgical clips in the head (particularly aneurysm clips)
Individuals with dental fillings or bridges, a replacement hip or knee, or tubal ligation clips are generally safe to have an MRI.
In most cases, a full exam of the foot and ankle via MRI lasts between 60 and 90 minutes.
