This workshop in Tokyo, Japan's political center since 1603 and a fascinating city with both a rich history and modern culture, will bring together the world's leading stakeholders in the field of osteoarthritis imaging. During four days of plenary sessions mixed with ample opportunities for informal interactions, attendees will be updated about latest scientific results and have the chance to engage in discussions on current challenges and priorities for future research. Since there will be participation of fundamental and clinical researchers, clinicians and industry representatives working with different imaging modalities, this workshop will cover a wide variety of topics spanning the range from technical development, validation, clinical application, image analysis, as well as industry and patient perspectives.
