1898年世界著名科学家居里夫妇成功地提取了放射性镭,这一划时代的科学发现,为后人点燃了放射性元素造福于人类的圣火。1927年,Blumgart等首先将放射性同位素注射入人体的一只手臂,在另一手臂测量放射性元素在体内循环的时间,从而间接测量了血液在体内循环的时间,打开了放射性核素诊断人类疾病及测定生理活动的大门,核医学学科从此而诞生。20世纪30年代, In 1898, the world famous scientist Marie Curie succeeded in extracting radium radium, a landmark science discovery that lit the radioactive element for the future generations to benefit human torch. In 1927, Blumgart et al. First injected radioisotope into one arm of the human body and measured the time of circulating radioactive elements in the other arm, thereby indirectly measuring the time when blood circulated in the body, turning on radionuclide to diagnose human diseases and Determination of physiological activity of the door, nuclear medicine from birth. 1930s,
