Sponsor's own description

Today, regular X-ray examination is not sufficiently sensitive for detecting progression of bone destruction in rheumatoid arthritis, but a new type of high-resolution CT scanner, the High-Resolution peripheral Quantitative Computed Tomography (HR-pQCT) can detect very early and minor joint injuries. The purpose of this study is to use HR-pQCT techniques to look at the damage and disease activity progression in the hand and wrist joints of patients with rheumatoid arthritis.
