Nuclear medicine is also called atomic medicine. It refers to the medical applications of radioactive isotopes, radiation beams generated by accelerators, and nuclear radiation produced by radioactive isotopes. In medical treatment, radioisotopes and nuclear radiation can be used for diagnosis, treatment, and medical scientific research. In pharmacy, they can be used for the study of the principle of drug action, measurement of drug activity, drug analysis, and radiation sterilization of drugs.
Nuclear medicine is a new discipline that uses nuclear techniques to diagnose, treat, and study diseases. It is a combination of modern science, technology and medicine in nuclear technology, electronic technology, computer technology, chemistry, physics, and biology. Nuclear medicine can be divided into two categories, namely clinical nuclear medicine and basic nuclear medicine or experimental nuclear medicine. The former is closely integrated with clinical departments and penetrates each other. Nuclear medicine can also be divided into cardiovascular and nuclear medicine, nuclear medicine, digestive system nuclear medicine, endocrine nuclear medicine, pediatric nuclear medicine and therapeutic nuclear medicine according to organs or systems. Since the 1970s, due to the development of single photon emission computed tomography and positron emission computed tomography, as well as the innovation and development of radiopharmaceuticals, nuclear medicine imaging technology has made a breakthrough. It complements and confirms each other with CT, MRI, ultrasound technology, etc. It greatly improves the diagnosis and research level of diseases. Therefore, nuclear medicine imaging is a very active branch and an important part in the field of modern clinical medical imaging diagnosis. .
