Thirty juvenile idiopathic arthritis cases with active clinical findings and ultrasound features of effusion and/or tenosynovitis were further imaged with power Doppler and SMI. For classification of synovial inflammation, a semiquantitative scale (4 points) adopted by Outcome Measures in Rheumatology was used.A total of 35 knee, 2 hip, 2 ankle, 2 wrist, 2 elbow joints, and 6 flexor hallucis longus/tibialis posterior tenosynovitis were assessed. In knee joint, power Doppler and SMI scales were the same for 23 (65.7%) joints, SMI upgraded scale from 0 to 2 in single joint (2.9%); 1 to 2 (14.3%) in 5 joints; and 2 to 3 (17.1%) in 6 joints. For other joints, power Doppler and SMI scales were the same for 5 (62.5%) joints. Superb microvascular imaging upgraded scale from 1 to 2 (25%) in 2 joints and 1 to 3 (12.5%) in a single joint. For flexor hallucis longus/tibialis posterior tenosynovitis, power Doppler and SMI scales were the same for two cases (33.3%). Superb microvascular imaging upgraded scale from 0 to 2 in two cases (33.3%); and 2 to 3 (33.3%) in 2 cases. There was no case of SMI scale downgraded compared with power Doppler scale.Superb microvascular imaging is a feasible technique in the assessment of synovial inflammation and tenosynovitis in juvenile idiopathic arthritis. Superb microvascular imaging has higher sensitivity compared with power Doppler ultrasound in depiction of increased vascularity.eninfo:eu-repo/semantics/closedAccessMusculoskeletal ultrasoundUltrasonographyPowerDefinitionsReliabilityChildrenJointsScoreJuvenile idiopathic arthritisSynovitisSuperb microvascular imagingDopplerScience & technologyLife sciences & biomedicineRadiology, nuclear medicine & medical imagingRadiology, nuclear medicine & medical imagingArticle000625801600010566237110.1097/RUQ.0000000000000516
