核磁共振(NMR)不使用X射线和核射线,属无创性方法,对机体无害,能获得体内任何部位的图像和代谢两类资料,故正迅速形成影像诊断和病理代谢研究的一个领域。众所周知,人体的70～80%是由水构成,故探测软组织内的微细改变特别有用的是~1H—MRI(1氢一磁共振显像)。除心肌和脑缺血的诊断外,对肿瘤的诊断也可发挥威力。由 Nuclear magnetic resonance (NMR) does not use X-rays and nuclear rays, is a noninvasive method that is harmless to the body and can obtain both image and metabolic information in any part of the body. Therefore, it is rapidly becoming an area of ​​imaging diagnosis and pathological metabolism research. It is well-known that 70-80% of the human body is made of water. Therefore, it is particularly useful to detect minute changes in the soft tissues by ~ 1H-MRI (1H-MR imaging). In addition to the diagnosis of myocardial and cerebral ischemia, the diagnosis of cancer can also play a role. by
