Introduction Technical Aspects Pediatric Aspects Guide to Scanning Regions Reporting and Scoring Integration into Clinical Flow Equipment and settings •The equipment (i.e. ultrasound machines, frequency of the probe) should be indicated in the report since it might influence the result of MSUS examination1 •Optimize image settings for B-mode (by adjusting frequency, depth, and focus) and Doppler ultrasound (the optimum frequency must be found in practice and not in theory; use low PRF and the lowest possible filters; set Doppler gain by turning it up untilrandom noise is encountered and then GEL lowering it untilthe noise disappears; place the focus where highest sensitivity is required)2 •The choice between color and power Doppler depends on the equipment2 •Transducer pressure may influence the flow; visible gel between the transducer and skin will ensure light pressure2 i TIP / Use a generous amount of gel. Cortical margins have to appear bright, sharp, and hyperechoic. Correct the size of the Doppler box, which has to contain the relevant joint structures and extend to the top of the image. 1.Möller I et al.Ann Rheum Dis 2017;76:1974–1979; 2.
