Definitions related to magnetic resonance imaging:
-
(mri) Imaging that uses radiofrequency waves and a strong magnetic field rather than x-rays to provide amazingly clear and detailed pictures of internal organs and tissues. The technique is valuable for the diagnosis of many pathologic conditions, including cancer, heart and vascular disease, stroke, and joint and musculoskeletal disorders.CDISC TerminologyClinical Data Interchange Standards Consortium (CDISC), 2021
-
A procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue. NMRI makes better images of organs and soft tissue than other scanning techniques, such as computed tomography (CT) or x-ray. NMRI is especially useful for imaging the brain, the spine, the soft tissue of joints, and the inside of bones.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021
-
A scan that creates detailed pictures of internal organs; commonly referred to as MRI. Magnetic resonance imaging uses radio waves, a strong magnetic field, and a computer to produce images of organs and internal tissues.Harvard Dictionary of Health TermsHarvard Medical Publishing, 2011
-
Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
MRI uses magnetic fields and radio waves to produce images of thin slices of tissues (tomographic images). Normally, protons within tissues spin to produce tiny magnetic fields that are randomly aligned. When surrounded by the strong magnetic field of an MRI device, the magnetic axes align along that field. A radiofrequency pulse is then...Merck & Co., Inc., 2020

Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body.Mayo Foundation for Medical Education and Research
-
Magnetic resonance imaging (MRI), three-dimensional diagnostic imaging technique used to visualize organs and structures inside the body without the need for X-rays or other radiation. MRI is valuable for providing detailed anatomical images and can reveal minute changes that occur over time. It...Encyclopedia Britannica, Inc., 2020
