Expected International Day of Radiology Deals

International Day of Radiology is primarily an observance for professional recognition and education, rather than consumer deals. However, medical imaging equipment manufacturers like Siemens Healthineers, GE HealthCare, and Philips Healthcare often highlight their innovations and support professional development programs. Professional societies such as the European Society of Radiology (ESR), the Radiological Society of North America (RSNA), and the American College of Radiology (ACR) host webinars, workshops, and offer discounted educational materials. Look for special events at hospitals and clinics recognizing their radiology departments. We will update this page with confirmed live deals as November 8 approaches.

Wilhelm Conrad Röntgen

Wilhelm Conrad Röntgen (1845–1923) was a German mechanical engineer and physicist who, on November 8, 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays. His groundbreaking discovery revolutionized medicine, allowing doctors to see inside the human body without surgery. He was awarded the first Nobel Prize in Physics in 1901 for this monumental achievement, forever changing diagnostic capabilities.

History of International Day of Radiology

Radiology, a discipline of medicine, utilizes medical imaging to diagnose and treat diseases that affect both animals and humans. On November 8, 1895, Wilhelm Conrad Röntgen, a German mechanical engineer and physicist, discovered x-rays by accident while exploring cathode rays, thereby establishing the groundwork for the medical specialty of radiology. Röntgen went on to discover and create electromagnetic radiation in the X-ray or Röntgen ray wavelength range, earning him the Nobel Prize in Physics in 1901.

The International Day of Radiology was established in 2011 as a follow-up to the European Day of Radiology. On February 10, 2011, the first and only European Day of Radiology (EDoR) was conducted to honor the anniversary of Röntgen’s death. The European Society of Radiology hosted the event. Following the European Day of Radiology’s success, the E.S.R. collaborated with the Radiological Society of North America and the American College of Radiology to create the International Day of Radiology. It was also determined that the anniversary of Röntgen’s death should be relocated to the anniversary of his discovery of the x-ray.

On November 28, 2011, the three founding societies formally recognized the day during the annual Radiological Society of North America meeting in Chicago. November 8 was eventually picked, and all radiological organizations around the world commemorate it.
