magnetic resonance imaging
Also known as NMRI, MRI, MRI scan, MR imaging, magnetic-resonance imaging, NMR imaging, nuclear magnetic resonance imaging
non-destructive technique for imaging internal structures of objects or organisms
AI overview
Magnetic resonance imaging is a non-destructive technique that uses magnetic fields to create detailed pictures of the internal structures inside objects or living organisms without damaging them. It matters because it allows doctors and researchers to see inside the body or examine materials in ways that don't require cutting, breaking, or otherwise harming what's being studied.

Article
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy.
MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, although "open" MRI designs mostly relieve this. Additionally, implants and other non-removable metal in the body can pose a risk and may exclude some patients from undergoing an MRI examination safely.
