INFLAMMATORY ARTHRITIS, DISEASE, ARTHRITIS
To summarize, the here-presented data indicate a good diagnostic performance of OST in the follow-up evaluations of patients with inflammatory arthritis. OST was able to assess response to therapy in a similar way to joint US and correlated significantly with arthritis activity markers. Joint US remains of course gold standard in the follow-up examinations of patients with arthritis, given its high sensitivity and overall diagnostic accuracy. However, OST can prove to be a valuable non-invasive, time- and resource-saving tool to also assist the monitoring of disease activity. Further data on this modern diagnostic modality are thus greatly needed.
