The more than 42,000 members of the American College of Radiology include radiologists, radiation oncologists, medical physicists, interventional radiologists and nuclear medicine physicians. For over three quarters of a century, the ACR has devoted its resources to making imaging safe, effective and accessible to those who need it. The mission of the ACR is to serve patients and society by maximizing the value of radiology, radiation oncology, interventional radiology, nuclear medicine and medical physics by advancing the science of radiology, improving the quality of patient care, positively influencing the socio-economics of the practice of radiology, providing continuing education for radiology and allied health professions and conducting research for the future of radiology.

The Radiological Society of North America (RSNA) is a non-profit organization that represents 31 radiologic subspecialties from 153 countries around the world. We promote excellence in patient care and healthcare delivery through education, research and technologic innovation. We provide high-quality educational resources, including continuing education credits toward physicians’ certification maintenance, host the world’s largest radiology conference and publish five peer-reviewed journals: : Radiology, RadioGraphics, Radiology: Artificial Intelligence, Radiology: Cardiothoracic Imaging and Radiology: Imaging Cancer. We are dedicated to building the future of our profession, whether that's through our Research & Education Foundation, which has funded $60 million in grants since its inception, our solutions to support standards development or educational outreach to low-resource nations.

The American Registry of Radiologic Technologists (ARRT) is the world’s largest organization offering credentials in medical imaging, interventional procedures, and radiation therapy. We certify and register technologists in a range of disciplines by overseeing and administering education, ethics, and examination requirements. We also advocate for safety and advancement in radiological sciences professions by supporting initiatives such as the Image Gently™ Alliance and by contributing to industry research studies.
