What should I know about a foot and ankle MRI?
Foot And Ankle MRI — What You Should Know. Magnetic resonance imaging, otherwise known as MRI, uses a combination of magnetic fields and radio waves to take images of the internal structures of your body. Your doctor, with the help of a radiologist, can then examine these images to determine whether there is anything wrong with your foot or ankle.
How is magnetic resonance imaging used to diagnose foot disease?
Magnetic resonance (MR) imaging has opened new horizons in the diagnosis and treatment of many musculoskeletal diseases of the ankle and foot. It demonstrates abnormalities in the bones and soft tissues before they become evident at other imaging modalities.
Where does MR imaging of the ankle take place?
Routine ankle MR imaging is performed in the axial, coronal, and sagittal planes parallel to the table top. The foot is imaged in the oblique axial plane (ie, parallel to the long axis of the metatarsal bones), oblique coronal plane (ie, perpendicular to the long axis of the metatarsals), and oblique sagittal plane (, Fig 1 ).
Do you need to be sedated for an ankle MRI?
However, if you suffer from claustrophobia, you may need to be sedated. Also, if you have any kind of metal implant or electronic device inside your body or on your person, it may interfere with the imaging process, and there is even a chance that it can create a safety hazard.
