Magnetic resonance imaging is a sophisticated diagnostic procedure to diagnose the following kinds of problems or conditions:
- Arthritis.
- Fractures.
- Infection.
- Injuries of the tendons, ligaments, or cartilage.
- Tumors.
MRIs use no radiation like conventional X-rays or CT scans. They employ a large magnet and radio waves to produce a kind of three-dimensional image. MRIs are very good at portraying soft tissues and bones in your feet and ankles.
People with the following conditions may not be good candidates for a MRI:
- A condition that requires a heart pacemaker.
- Electronic inner ear implants.
- Electronic stimulators.
- Implanted pumps.
- Metal fragments in your eyes.
- Some artificial heart valves.
- Surgical clips in your head (particularly aneurysm clips).
If you have a dental filling or bridge, a replacement hip or knee, or tubal ligation clips, you are usually safe to have a MRI.
In most cases, a full exam of the foot and ankle last between one hour to 90 minutes.
