What is an MRI?
Magnetic Resonance Imaging or MRI is a painless, non-invasive, radiation-free diagnostic procedure that uses a powerful magnet, radio frequency, and an advanced computer system to create detailed images of the organs and structures of the body. The MRI scanner consists of a patient bed surrounded by encased magnets which create a strong magnetic field around the patient. An MRI provides doctors with high quality images they can use to diagnose and evaluate your physical condition by tailoring your exam to answer the specific medical question being asked.
