This year, on November 8, the European Society of Radiology (ESR), the Radiological Society of North America (RSNA) and the American College of Radiology (ACR) will celebrate the first International Day of Radiology (IDoR 2012), along with radiological societies the world over. This initiative was established with the aim of building greater awareness of the value that radiology contributes to safe patient care, and improving understanding of the vital role radiologists play in the healthcare continuum.
