Wilhelm Roentgen
November 8, 2019 — Nov. 8 marks 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 European Society of Radiology (ESR), and the American College of Radiology (ACR).
Held each year on Nov. 8 — 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 RadiologyInfo.org, 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 hundreds of radiology procedures. It also provides information on diseases and conditions, screening and wellness, and safety topics.
For this year’s celebration, ESR launched a new sports imaging microsite to show the general public how radiology is used in the diagnosis and management of sports injuries with reference to the real-life experience of 28 athletes from a selection of the world’s most popular sports.
