核磁共振(Nucleaf Magnetic Resonance 简称NMR)现象的发现至今有30多年历史。核磁共振在医学中,作为诊断技术包括2个方面,即普通的核磁共振波谱学与核磁共振成像技术。前者通过某些原子核的化学位移,用以测定组织代谢作用;后者是把体内组织中的氢质子的浓度或其它特性予以描绘,产生一种类似电子计算机断层(CT)的扫描图像而用以诊断疾病。核磁共振成像技术近年来发展
The discovery of nuclear magnetic resonance (NMR) phenomenon has been more than 30 years old. Nuclear magnetic resonance in medicine, as a diagnostic technique includes two aspects, namely ordinary nuclear magnetic resonance spectroscopy and magnetic resonance imaging technology. The former is used to determine tissue metabolism by chemical shifts of certain nuclei; the latter is to map the concentration of hydrogen protons in the body tissue or other characteristics to produce a scanning image resembling a computed tomography (CT) Diagnose the disease. Magnetic resonance imaging technology has developed in recent years
