磁共振成像术,是根据核磁共振(NuclearMagnetir Resonance,简称 NMR)现象的原理,将电波信号收入复杂的成像系统形成图像的技术,近几年来已应用于临床。(NMR 是1946年由美国学者 Bloch 和 Purcell发现的,这是一项获得1952年诺贝尔奖的物理学成果。某些原子核(如氩的原子核)在外加 Magnetic resonance imaging (MRI) is a technique of forming an image based on the principle of Nuclear Magnetic Resonance (NMR) phenomena and incorporating a radio wave signal into a complicated imaging system and has been used clinically in recent years. (NMR was discovered by American scholar Bloch and Purcell in 1946 as a physics result that won the Nobel Prize in 1952. Some nuclei (such as Argon nuclei)
