According to the latest Assessment of Spondyloarthritis International Society criteria, imaging is a key way to diagnose peripheral seronegative SpA. Common imaging features are enthesitis, synovitis, tenosynovitis, erosive and bone-proliferative changes in the affected joints, and effusion.Although magnetic resonance imaging is the gold standard technique, ultrasound (US) is a cost-effective imaging method that can readily detect the features just described. Additionally, it can semi-quantify inflammatory changes, helping in treatment and dose modifications. Imaging-guided procedures, such as biopsies and steroid injections, are routinely performed using US. Furthermore, US can easily be deployed at outpatient rheumatology clinics, making it an ideal point-of-care investigation.</p>","PeriodicalId":49545,"journal":{"name":"Seminars in Musculoskeletal Radiology","volume":"28 6","pages":"740-748"},"PeriodicalIF":0.9,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142677584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
