noun
magnetic resonance tomography; MRT
Medical imaging technique that uses magnetic fields and radio waves to produce cross-sectional images of the body. Often referred to as MRI (magnetic resonance imaging) in English, though technically MRT emphasizes the tomographic aspect.
医師は磁気共鳴断層撮影の結果を詳しく説明した。
The doctor explained the results of the magnetic resonance tomography in detail.
MRI is the more common English abbreviation for magnetic resonance imaging, while 磁気共鳴断層撮影 is the full Japanese term. In Japanese medical contexts, MRI is also widely used as a loanword.
CT (computed tomography) uses X-rays, whereas 磁気共鳴断層撮影 uses magnetic fields and does not involve ionizing radiation.
Compound of 磁気 (magnetic), 共鳴 (resonance), 断層 (tomography, literally 'slice layer'), and 撮影 (imaging, photography). The term is a direct translation of the English 'magnetic resonance tomography'.
