What is an MRI?

Magnetic resonance imaging (MRI) is a non-invasive exam that allows physicians to look inside the body to diagnose medical conditions. It is an important exam that can lead to early detection and treatment of disease.

MR imaging uses a powerful magnetic field to produce detailed pictures of organs, soft tissues, bone and other internal body structures. The images can then be examined on a computer monitor. There is no radiation used with an MRI exam.

Detailed images allow physicians to better evaluate parts of the body and determine whether there is a certain disease present. MRI is more accurate at diagnosing certain diseases that may not be assessed adequately with other imaging exams such as x-ray, ultrasound or CT scans.
