November 2017


The International Day of Radiology (IDOR) was celebrated for the sixth time on November 8, this year focusing on emergency radiology and was joined by supporters all around the world. 

More than 160 radiology-related professional societies from around the world participated in the International Day of Radiology 2017, holding a range of different events to celebrate, such as public lectures, department open days, national media appearances, and press events. A comprehensive list can be found on the IDOR homepage.

The new IDOR book ‘HELP - Emergency Medical Imaging’ was published on November 8 as downloadable pdf and has already been downloaded more than 1,500 times within the first five days. Under the editorial leadership of Professor Robert F. Dondelinger from Liège, Belgium, 42 authors from all over the world contributed to the book, with further chapters provided by the ESR’s EuroSafe Imaging initiative, the European Federation of Radiographer Societies (EFRS) and the ESR Patient Advisory Group. In addition, 30 interviews with emergency radiology experts from different countries, conducted by the ESR, have been published on the IDOR webpage.

On social media, the International Day saw tremendous feedback throughout various platforms. The IDOR Facebook page, which shared a variety of events, fan posts and general IDOR information, attracted 7,800 likes on IDOR related posts and gained over 2,000 new fans with a peak during the days before the actual event.
On Twitter, which has traditionally seen the biggest buzz for IDOR related social media activities, 5,200 tweets including the hashtag IDOR 2017 have been tweeted, generating a user feed reach of 24.3 million. In comparison to last year, the IDOR hashtag appeared three million times more often in Twitter users’ feeds.
For the fourth time, the ESR organised a Thunderclap campaign for IDOR 2017. Thunderclap is a tool for amplifying a message on social media. By supporting the Thunderclap, users agreed to share the same message at the same time as everyone else on their Facebook, Twitter or Tumblr pages, giving the message much more prominence and priority on social media feeds than individual posts. The Thunderclap message was released on November 8, 14:00 CET by 423 supporters to a combined audience of 667,537 people.

To bring the IDOR 2017 main topic emergency radiology to the public’s attention, the ESR has created a mini website acting as an online emergency room to show examples of emergency cases, with images and explanations of how radiologists’ expertise comes into play. Content and cases were developed in cooperation with Dr. Elizabeth Dick, President-Elect of the European Society of Emergency Radiology. Users can explore four body regions – abdomen, chest, head & neck, limbs – with three different cases/modalities for each region.

The same application is currently running on a touch screen window on the ground floor of the ESR office in Vienna where interested passers-by can find out more about emergency radiology and its daily use.

The ESR celebrated IDOR 2017 with an internal staff event at its office and was joined by participants of the ESOR for EDiR Courses, which took place throughout the week in the ESR learning centre located on the same premises. Professor Michael Fuchsjäger, from Graz/Austria, gave introductory words in his capacity as chair of the ESR Communication & External Affairs Committee and a temporary IDOR 2017 projection was visible on a building opposite the ESR office during the event. 

IDOR 2018 will be celebrated on November 8, 2018 and will feature cardiac imaging as its main topic.
