First and oldest radiology society in the United States. The American Roentgen Ray Society, founded in 1900, is the first and oldest radiology society in the United States.
The society has been a forum for progress in radiology since shortly after the discovery of the X-ray and is dedicated to the goal of the advancement of medicine through the science of radiology and its allied sciences. The goal of the ARRS is maintained through an annual scientific and educational meeting, through publication of the American Journal of Roentgenology, and through other educational symposia. The Annual Meeting consists of instructional courses, scientific paper presentations, a symposium, a new issues forum, scientific exhibits, and commercial exhibits. A special categorical course and annual Case-Based Review Course is also offered. Category 1 CME credits are available on an hour-for-hour basis. All members of the Society may attend the Annual Meeting with discounted payment of the general registration fee. The monthly American Journal of Roentgenology (AJR) is a highly respected peer-reviewed journal with a worldwide circulation of more than 25,000. For more than 100 years, the AJR has been recognized as one of the best specialty journals in the world. The quarterly ARRS InPractice magazine keeps members informed of Annual Meeting plans and general Society information. The Society invests in the future of radiology by awarding scholarships and awards to deserving individuals through the Roentgen Fund.
Mission: The Society’s mission is to improve health through a community committed to advancing knowledge and skills in radiology.
