Thus, it can be said that KSNM follows the academic mainstream of nuclear medicine. Young pioneers including Munho Lee, Jang-Kyu Lee, Ki-Seok Hwang, Byung-Seok Min, and Chang-Soon Koh founded KSNM on December 28, 1961. Prof. Munho Lee was elected the first president of KSNM. The Korean Journal of Nuclear Medicine, the former title of NMMI, was first published in March 1967. In the late 1960s, static and dynamic nuclear imaging became available by installing gamma cameras in pioneering hospitals in Korea. Thyroid scan, liver scan, hepatobiliary scan, brain scan, and serial renal scan were major imaging studies in nuclear medicine. In the late 1970s, quantification of static and dynamic images became available after installing a computer system to gamma cameras. SPECT cameras were introduced after the mid-1980s, which were mainly practical for blood flow analyses of the brain and myocardium. In the mid-1990s, positron emission tomography (PET) and medical cyclotron were first introduced in Korea [1, 2]. With these new methodologies, nuclear medicine physicians have focused on functional and metabolic images of various organs. Anatomical images such as X-ray, ultrasound, CT, and MRI have been used widely in patient management. However, morphologic changes usually appear lately following functional and metabolic changes in many disorders. Thus, molecular and genetic imaging using radionuclide technology is investigated to prepare future molecular medicine. Genetic imaging seeks out the fundamental cause of a disease and the truths on the disease or even life. As the belief of Mahatma Gandhi, “Truth is god”, molecular and genetic imaging enables us to broaden our knowledge and hopefully to explore inventor of the cosmos. With the expansion of nuclear medicine–based imaging and therapy in clinic, the Korean Specialty Board of Nuclear Medicine was established in 1995 [1]. After the separation of nuclear medicine as an independent medical specialty, many young physicians and scientists assembled in the field. In addition to board members from the regular training course of nuclear medicine, specialists in internal medicine or radiology
