Quantitative computerized joint scanning in rheumatoid arthritis: an accurate reproducible method of quantitating...

Clinical trials in rheumatoid arthritis have been hampered by the highly subjective nature of disease assessment measures and lack of a consistently reliable laboratory test to follow. The authors devised a method of quantitating synovitis by computerized joint scanning and compared it with six conventional parameters in 18 patients entered into two treatment protocols and a control group. The results indicate that quantitative joint scanning probably is at least as reliable as the conventional measures and has the advantage of having no placebo or subjective component.
