What is an MRI?
Magnetic resonance imaging (or MRI) is a non-invasive medical imaging technique that uses powerful magnetic fields and radio waves to take high-quality pictures of your organs and body.
MRI scanners are large magnets that create strong magnetic fields around the part of the body being imaged. The magnetic field made by an MRI scan is used to create a detailed image of the inside of your body that doctors can use to assess and diagnose your condition. In contrast to X-ray machines or computed tomography (CT scan) machines, MRIs do not use X-rays or ionizing radiation.
