OAK BROOK, Ill. (Nov. 8, 2018) – Today is International Day of Radiology (IDoR), celebrated around the world in recognition of the remarkable contributions made by medical imaging to health care, and the role of radiology professionals in providing quality care to patients. The day is sponsored by the Radiological Society of North America (RSNA), the American College of Radiology (ACR) and the European Society of Radiology (ESR) and is observed by nearly 170 international radiology societies through public lectures, press events and other activities.

Held each year on November 8th—the anniversary of the discovery of the X-ray by German physicist Wilhelm Roentgen—IDoR is building greater awareness of the value that radiology research, diagnosis and treatment contribute to safe and effective patient care.

IDoR recognizes the many innovations in radiology research that have revolutionized modern medicine, produced great technological advances and saved countless lives.

Radiology professionals are working together throughout the year to inform patients about the valuable role medical imaging plays in patient care. RSNA and ACR jointly sponsor, an important patient resource that explains medical imaging tests and treatments in detailed, easy-to-understand language, helping patients to understand and prepare for imaging procedures. The site contains explanations of more than 240 disease and conditions and radiology procedures. It also provides information on screening and wellness and safety topics.
