多年来,物理学家用核磁共振法来分析溶液的化学成分。目前这种方法也应用到医学诊断方面来了,英国的一家公司研究了检查肿瘤的核磁共振仪器。牛津大学的科学家使用这种方法对心、肾和脑的功能进行检查。通常,核磁共振法是用来检查氢原子的。在人体组织内氢原子与氧是密切相关的,二者在一起构成水。多数组织内都含有水,所以通过氢原子分布的分析,能收得一幅非常清晰的器管结构图象。Notting ham大学的研究人员不用X射线和放射线同位素,而用核磁共振的方法显示出脏器结构的电视图象。牛津大学生物化学系研究小组在George Radda博士的领导下,用核磁共振方法对器管中的磷原子进行了研究。磷是器管中的重
For years, physicists used NMR to analyze the chemical composition of solutions. At present, this method is also applied to medical diagnosis. A British company has studied the MRI instrument for tumor examination. Oxford University scientists use this method to examine heart, kidney and brain function. In general, NMR is used to examine hydrogen atoms. Hydrogen atoms in human tissues are closely related to oxygen, and the two together form water. Most organizations contain water, so by analyzing the distribution of hydrogen atoms, can get a very clear tube structure images. Researchers at Nottingham University did not use X-rays and radioactive isotopes, but used nuclear magnetic resonance to visualize images of organs. Under the leadership of Dr. George Radda, Ph.D., Ph.D., Ph.D., of the Department of Biochemistry, University of Oxford, studied the phosphorus atoms in the tube using NMR spectroscopy. Phosphorus is the weight of the tube
