magnetic resonance imaging n.
The use of a nuclear magnetic resonance spectrometer to produce electronic images of specific atoms and molecular structures in solids, especially human cells, tissues, and organs.
|magnetic resonance imaging |
A technique for forming detailed images of internal organs and tissue. It works by putting the patient inside a magnet, then using radio waves to locate atoms in the tissue. Final production of the image is done by a computer. (Compare x-ray and ultrasound.)
Note: MRI images are the most detailed that can be obtained.
three-dimensional diagnostic imaging technique used to visualize organs and structures inside the body without the need for X-rays or other radiation. Magnetic resonance imaging (MRI) is valuable for providing detailed anatomical images and can reveal minute changes that occur over time. MRIs can be used to detect structural abnormalities that appear in the course of a disease, as well as how these abnormalities affect subsequent development and how their progression correlates with mental and emotional aspects of a disorder. Since MRI poorly visualizes bone, excellent images of the intracranial and intraspinal contents are produced.
