RadiologyInfo™ is the public information website developed and funded by the Radiological Society of North America (RSNA) and the American College of Radiology (ACR). It was established to inform and educate the public about radiologic procedures and the role of radiologists in healthcare, and to improve communications between physicians and their patients.
RadiologyInfo is dedicated to being the trusted source of information for patients, families and health care providers about the vital role of medical imaging, image-guided therapy and radiation therapy in health care. To ensure its quality and accuracy, each section has been created with the guidance of a physician with expertise in the topic presented.
