What is an MRI scan?

An MRI, or magnetic resonance imaging, shows healthcare professionals a detailed, three-dimensional image to help form an accurate diagnosis of what is going on inside a particular part of the body. The procedure uses magnetic fields and radio waves to capture the image; unlike CAT scans and traditional X-rays, it does not subject the patient to radiation. Each scan takes a few minutes, with an entire MRI lasting for about 45 to 90 minutes, depending on the body part involved.

What is are they used for?

A podiatrist would use the scan to view what is happening inside of the foot or ankle to accurately diagnose a variety of health conditions or problems, such as bone fractures, arthritis, infections, growths, or damage to nerves and/ or soft tissues that traditional X-rays cannot detect.

Is there any risk involved?

Certain physical conditions prohibit the use of MRIs in some patients, since the magnetic force can attract metal implants. For example, those with pacemakers, artificial heart valves, and some types of surgically-implanted pumps, stimulators, hearing devices, and surgical clips may not be able to have an MRI performed. Also, if a patient has metal fragments in his or her eye, an MRI cannot be performed. This information would be disclosed in a patient’s questionnaire responses that are gathered prior to performing any imaging tests.
