Magnetic resonance imaging
A procedure that uses magnetism, radio waves, and a computer to create pictures of areas inside the body. Abbreviated MRI. An MRI is painless and has the advantage of avoiding x-ray radiation exposure. There are no known risks of an MRI. The benefits of an MRI relate to its precise accuracy in detecting structural abnormalities of the body. Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet.

A special type of magnetic resonance imaging (MRI) that uses an injected dye in order to see blood flow through tissues.
- Magnetic resonance spectroscopic imaging
(MRSI) A noninvasive imaging method that provides information about cellular activity (metabolic information). It is used in oncology along with magnetic resonance imaging (MRI) which provides information about the shape and size of the tumor (spacial information). Also called 1H-nuclear magnetic resonance spectroscopic imaging and proton magnetic resonance spectroscopic imaging.
- Magnetic-targeted carrier
A tiny bead made from particles of iron and carbon that can be attached to an drug. A magnet applied from outside the body then can direct the drug, for example, to the site of a tumor. This can keep a larger dose of the drug at the tumor site for a longer period of […]
