What is an Magnetic Resonance Imaging (MRI)?Magnetic Resonance Imaging (MRI) is a non-invasive method of imaging that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI exams give different information about structures in the body than can be seen with an x-ray, ultrasound or computed tomography (CT) scan. MRI scans may also show problems that cannot be seen with other imaging methods.
The area of the body being studied during an MRI is placed inside a special machine that contains a strong magnet. Pictures from an MRI scan are digital images that can be saved and stored on a computer for more study. The images can also be reviewed remotely, such as in a clinic or an operating room. In some cases, contrast material may be used during the MRI scan to show certain structures more clearly.
