Synovitis was evaluated semi-quantitatively (0\u20133) by grey scale (GS) and power Doppler (PD) in 24 joints [both hands (wrist, metacarpophalageal, and proximal interphalangeal joints) and both shoulder joints].<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall, 18 patients had rheumatoid arthritis (25.0%); the mean age was 75.0\u2009years, and 34.7% and 65.3% were male and female, respectively. In PMR and PMR\/EORA groups, multivariate logistic analysis showed that rheumatoid factor positivity, GS \u22652 of hand joints, and PD \u22651 of hand joints were independent factors with significant differences.
