International Day of Radiology to Recognize More than a Century of Lives Saved and Improved by Radiologists and Medical Imaging


American Society of Neuroradiology (ASNR) is proud to participate in the first annual International Day of Radiology — November 8, 2012 — marking the 117th anniversary of the discovery of the X-ray and the tremendous advances in patient care made possible by radiation therapy and medical imaging exams, such as magnetic resonance imaging (MRI) and computed tomography (CT).

ASNR joins more than 66 medical societies in 38 countries around the globe taking part in this celebration of radiology, sponsored by the European Society of Radiology (ESR), the Radiological Society of North America (RSNA) and the American College of Radiology (ACR).

More than a century of radiologic research has produced great technological leaps, enabled more effective and efficient care, saved countless lives and revolutionized modern medicine:

  • The New England Journal of Medicine named imaging among the top 10 medical advances of the last 1,000 years.
  • Imaging scans have virtually eliminated exploratory surgeries, reduced unnecessary hospital admissions and often shorten hospital stays.
  • According to the National Bureau of Economic Research, access to medical imaging is directly linked to greater life expectancy. Those with greater access to scans live longer than other Americans.
  • Practicing physicians surveyed in a Health Affairs study ranked CT and MRI as the top recent medical innovations.

Radiology professionals are working together to inform patients about the critical role medical imaging plays in patient care. One important resource is, an informational site sponsored by RSNA and ACR that explains medical imaging tests and treatments in detailed, easy-to-understand language, helping patients to understand and prepare for imaging procedures.
