放射性核素及核射线在医学中的应用是原子能和平利用的重要方面。它涉及到预防、诊断、治疗和科研等许多领域。现在已形成一门新兴的学科——核医学。核医学是现代医学的重要组成部分,是医学现代化的主要标志之一。它能动态地证明人体许多代谢途径,开扩人们的眼界,从过去静态的、片面的认识走向动态的、较全面的认识,为正确了解人体原有的生理生化功能,疾病的病因、过程和转归,开辟了新的途径。放射性核素或核射线能应用于脏器显象(扫描)、功能测定、体内微量物质定量、追踪体内代谢物质等许多方面。
The application of radionuclides and nuclear rays in medicine is an important aspect of the peaceful use of atomic energy. It involves many areas of prevention, diagnosis, treatment and research. Now a new discipline has formed - nuclear medicine. Nuclear medicine is an important part of modern medicine and one of the main symbols of medical modernization. It can dynamically prove that the body’s many metabolic pathways, open up people’s horizons, from static, one-sided understanding of the past to a dynamic, more comprehensive understanding of the human body to understand the physiological and biochemical functions correctly, the etiology and pathogenesis of the disease and Going forward, opening up new avenues. Radionuclides or nuclear rays can be applied to visceral imaging (scanning), functional assays, quantification of trace substances in the body, tracking of metabolites in the body, and many others.
