Detection of synovial inflammation in rheumatic diseases using superb microvascular imaging: Comparison with conventional power Doppler imaging

Aim: Superb microvascular imaging (SMI), a novel ultrasonography, is based on the sensitivity of Doppler technology. This study evaluated power Doppler (PD) ultrasound signals in patients with rheumatic disease using SMI and conventional PD imaging (cPDI) and compared the correlations of these signals to clinical assessments. Methods: Thirty-nine patients with rheumatic disease (27 rheumatoid arthritis [RA] and 12 non-RA) were enrolled. We...
