International Day of Radiology

First medical X-ray by Wilhelm Röntgen of his wife Anna Bertha Ludwig’s hand

The International Day of Radiology (IDoR) is an annual event which is  promoting the role of medical imaging in modern healthcare. This day is  celebrated on November 8 each year and coincides with the anniversary of the discovery of x-rays. It has been first introduced in 2012, as a joint initiative, by the European Society of Radiology (ESR), the Radiological Society of North America (RSNA), and the American College of Radiology (ACR).

Wilhelm Conrad Röntgen  (27 March 1845 – 10 February 1923) was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays. For this achievement he earned the first Nobel Prize in Physics in 1901.  In honour of his accomplishments, in 2004 the International Union of Pure and Applied Chemistry (IUPAC) named element 111, roentgenium, a radioactive element with multiple unstable isotopes, after his name.

The International Day of Radiology is a successor to the European Day of Radiology which has been launched in 2011. The first and only European Day of Radiology was held on February 10, 2011 to commemorate the anniversary of Röntgen’s death. The European day was organised by the ESR, who later entered into cooperation with the RSNA and the ACR to establish the International Day of Radiology.

The day is celebrated every year with events in many countries, mostly organised by national professional societies which represent radiologists.  The celebration of the International Day of Radiology hopes to aware the world to the stunning medical, scientific and even artistic possibilities of medical imaging, the essential role of the radiologist as a part of the healthcare team in numerous medical scenarios, and the high educational and professional standards  which are  required to the staff working in medical imaging, which is one of the most exciting and progressive disciplines in healthcare and a field of great activity in terms of technological and biological research. X-rays, MRI scans, ultrasound and many other  medical imaging technologies, as well as the impressive images associated with them, are known to the public, but the exact purpose and value of these services is not widely comprehended.


“Radiographers worldwide can use the day and the days around the date to promote radiography as a career, as a vital contribution to modern healthcare and as a chance to increase public awareness of diagnostic imaging and radiation therapy. ” – The Society of Radiographers- UK 


This year the day is dedicated to emergency radiology and the essential role that radiologists play in the emergency room, increasing the quality of care and treatment of patients.



Happy International Day of Radiology, wherever you are! 🙂
