The Arthritis Imaging Research Group is a network of researchers from the Department of Radiology of the Charité Medical Faculty, Berlin. The group was founded in 2010 by Kay G. Hermann, MD, who has been leading the group ever since. Torsten Diekhoff, MD, is deputy head of the working group. Numerous research topics are addressed by the group, including new methods of magnetic resonance imaging, computed tomography, sonography and projection radiography. This research is particularly aimed at early detection of rheumatic diseases such as rheumatoid arthritis, psoriatic arthritis, spondyloarthritis, gout, CPPD arthropathy and vasculitis. Special emphasis is given to the best possible image quality.

As a result of this work, the group is well established internationally within the framework of OMERACT, ASAS, ESSR and ESR and is valued by the pharmaceutical industry as a reliable partner for the implementation and evaluation of imaging.

A second focus of the Arthritis Imaging Research Group is interactive training in the field of rheumatological imaging. With the iPad-based classroom system BerlinCaseViewer, more than 200 hands-on courses have already been held worldwide.

Since 2014, we have been developing a web server and an app under the BerlinCaseViewer brand, which we use as part of our interactive training courses, mainly in the field of magnetic resonance imaging. Countless rheumatologists, orthopaedists and radiologists have already been trained with our system during one of more than 200 courses worldwide.

The system will soon also be publicly available as an app for iPads. Read more...
