The Los Angeles Radiological Society (LARS), founded in 1921, is dedicated to the promotion of high standards of practice in medicine overall with a focus primarily on radiology and radiation oncology. Members of the society adhere to the medical and ethical standards of the practice adopted by the American College of Radiology. The society promotes high stands through an active continuing medical education program by providing its members with the latest information on practice management and socioeconomic issues, by representing the radiological community to insurance carriers and government agencies, and through a public education program designed to communicate the value and importance of radiology and radiation oncology.
The society is composed of 580 full-time diagnostic radiologists, radiation oncologists, medical physicists, and technologists. Their standards of excellence are unmatched in the community and our membership includes some of the world’s most prominent physicians, both in the practice of radiology and oncology, as well as in related research teaching, and the development of new procedures and techniques. Membership in the Los Angeles Radiological Society is the entrance to organized radiology, including the California Radiological Society (CRS), the American College of Radiology (ACR), and the American Society for Therapeutic Radiology and Oncology (ASTRO). Organized Radiology exists to promote the standards of excellence in practice and science and to assure that radiology is treated fairly in political and socioeconomic deliberations. LARS includes the Southern California Radiation Oncology Society, whose radiation oncologists are full partners in the leadership of LARS.
