本総説の目的は，日本での心臓核医学の軌跡を筆者の経験に基づいて辿ることである。全国核医診療実態調査が日本の心臓核学診療の実態と経年的変化を記録している。過去約60年間日本の核医学の歩みを見てきた筆者の体験に基づいて，この間の心臓核医学画像の変遷と進歩を記録し，装置と放射性医薬品の進歩と多分野の専門家の協働が今後の心臓核医学の発展を推進することを示したい。
Practice of nuclear medicine (NM) in Japan started in 1950 when radioisotopes (RIs) were imported from the U.S.A. and Japan Radioisotope Association (JRIA) launched with the purpose for bulk buying and distribution of RIs to each user. The author has experienced the nuclear medicine practices since its dawn to present. The purpose of this historical review is to follow tracks of nuclear cardiology in Japan as seen by the author. The nation-wide survey of nuclear medicine practice in Japan which was conducted by a subcommittee of JRIA tells us numbers of examinations, instruments and radiopharmaceuticals used for cardiac imaging and their temporal changes. The author describes his experiences with cardiac imaging in NM and its chronological changes in accordance with developments of imaging devices and radiopharmaceuticals used. The author believes the new developments in instrumentations and radiopharmaceuticals together with multi-disciplinary cooperation will facilitate nuclear cardiology and contribute to welfare of patients.
