This study was undertaken to evaluate the diagnostic value of B\u2010mode sonography and power Doppler compared with that of clinical examinations and conventional radiography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The study group comprised 47 patients (14 men, 33 women) with different grades of RA; 31 patients were rheumatoid factor (RF) positive, and 16 were RF negative. The wrists, first through fifth metacarpophalangeal joints, and second through fifth proximal interphalangeal joints of these patients were scored with ultrasound in B\u2010mode and power Doppler application, using a standardized technique. Involvement and severity of inflammation, as well as vascularization, were scored according to a new 3\u2010point scale. The results were correlated with benchmarks of the clinical and radiologic investigations. Clinical status and conventional radiologic status were determined according to the Disease Activity Score and the Larsen score.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After preliminary studies in 15 patients, 39% of 704 joints were found to be abnormal by clinical investigation. Erosions were detected by radiography and sonography in 23% and 43% of joints, respectively. Hypervascularization was observed in 34% of 704 joints by power Doppler application. There was a significant correlation (<jats:italic>P<\/jats:italic> &lt; 0.001) between the different methods for the detection of the severity of lesions. Use of a modern, state\u2010of\u2010the\u2010art power Doppler program was necessary for semiquantification, and a standardized investigation technique and scoring system provided sufficient quality measures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Sonography detects 20% more abnormalities than does radiography, and sonography has the potential to provide simple grading of disease activity. The rate of detection of abnormalities was slightly higher with clinical examination compared with sonography.<\/jats:p><\/jats:sec>","DOI":"10.1002\/art.10784","type":"journal-article","created":{"date-parts":[[2003,2,7]],"date-time":"2003-02-07T07:09:02Z","timestamp":1044601742000},"page":"325-333","source":"Crossref","is-referenced-by-count":125,"title":["Diagnostic
