The International Diagnostic Course in Davos (IDKD) offers a unique learning experience for imaging specialists in training as well as for experienced radi­ ologists and clinicians wishing to be updated on the current state of the art and the latest developments in the fields of imaging and image-guided interventions. This annual course is focused on organ systems and diseases rather than on modalities. This year's program deals with neuroradiology and radiology of the spine. During the course, the topics are discussed in group seminars and in ple­ nary sessions with lectures by world-renowned experts and teachers. While the seminars present state-of-the-art summaries, the lectures are oriented towards fu­ ture developments. These proceedings represent a condensed version of the contents presented un­ der the 20 topics dealing with imaging and interventional therapies in the neuro­ radiology and radiology of the spine. The topics encompass all the relevant imag­ ing modalities including conventional x-rays, computed tomography, nuclear medicine, ultrasound and magnetic resonance angiography, as well as image-guid­ ed interventional techniques. The volume is designed to be an "aide-memoire" for the course participants so that they can fully concentrate on the lectures and participate in the discussions without the need of taking notes.
