The superb microvascular imaging is more sensitive than conventional power Doppler imaging in detection of active synovitis in patients with rheumatoid arthritis

This study evaluated Superb Microvascular Imaging (SMI) technology for detection of active synovitis in patients with rheumatoid arthritis (RA). Between June 2015 and October 2016, 56 patients with RA (42 females; mean age, 53.2 years) underwent gray-scale ultrasound (US) imaging, power Doppler imaging (PDI), and SMI for synovitis of both wrists and hands (total 22 joints), scored for each joint from grades 0 to 3. The sum of grades for 22...
