SONAR („Swiss Sonography Group in Arthritis and Rheumatism“) is a musculoskeletal ultrasound expert group founded in 2008. The group has developed a semi-quantitative score for Rheumatoid Arthritis using modified OMERACT
criteria for synovitis, tenosynovitis and erosions.
The score includes B mode and Powerdoppler mode in finger joints, wrists, elbows and knees, an erosion and tenosynovitis score and additional cartilage measurement in selected joints.
2015 we developed and introduced a semi-quantitative score for hip involvement in Spondyloarthritis and started teaching the score to rheumatologists nationwide (Sonar-Hip or CoxSonar Score).
This 4. edition (1. english edition) of the Sonar handbook explains the semi-quantitative Sonar score for Rheumatoid Arthritis and the 2015 introduced Sonar-Hip Score in SpA.
