MRI

Magnetic Resonance Imaging (MRI) uses a strong magnetic field to temporarily realign hydrogen atoms in your body. Directed radio waves cause these aligned atoms to produce faint radio signals, which are used to form detailed cross-sectional images.

The presence of any metal in the body may be a safety hazard. Before receiving an MRI, tell the technologist if you have any metal or electronic implants.

In some studies a contrast material may be injected through an intravenous (IV) line. Tell your doctor if you've ever had any allergic reactions to contrast agents, or if you have any kidney or liver problems.
