The International Diagnostic Course Davos (IDKD) was founded in 1969 with the aim of organizing annual postgraduate teaching courses in Diagnostic Radiology. The IDKD prides itself in its motto: “Excellence in Teaching”. The course programs are organ-based with the following topics, repeated every 4 years: Brain, Head & Neck, Spine - Chest, Breast, Heart and Vessels - Musculoskeletal Diseases - Abdomen & Pelvis. The Davos courses consist of highly interactive workshops, highlight lectures and a Film Reading Panel, which is a competition of eminent teachers in radiology, who solve interesting and difficult diagnostic problems by interpreting imaging studies in front of the audience. The program is completed by an exhibition of recently developed industrial products and current educational texts. The "Fundamentals in Imaging: From Head to Toe" lecture-style full day refresher course and the Pediatric Radiology course take place one day before the IDKD course. The scientific program of the course is led by the IDKD Course Directors: Prof. Juerg Hodler, MD, MBA; Prof. Rahel Kubik-Huch, MD, MPH; and Prof. Gustav von Schulthess, MD, PhD, MD hon. Teachers at the course are some 50 internationally renowned experts who in the workshop teach the students in groups of up to 60. The case viewing is supported by a special software, uniquely developed for the IDKD and drawing from the extensive expertise with electronic teaching. Participants also receive a course book (syllabus), representing a condensed version of the workshops in printed form. The courses in Davos are counting an average annual number of 1000 participants. In addition to the course in Davos, IDKD is running shorter, so called “intensive courses” in Athens, Beijing, Hong Kong, and Sao Paulo. IDKD is a Swiss non-profit organization, which is called “Foundation for the Advancement of Education in Medical Radiology” with a domicile in Wallisellen, Canton of Zurich.
