Reliability of colour Doppler ultrasonography of the major salivary glands in Sjögren's disease

Clin Exp RheumatolPublished Reliability study

Authors' conclusion

CD SGUS is a reliable imaging technique to visualise intraparenchymal vasculature in patients suspected of SjD, and therefore could be an asset in daily clinical practice. It requires, however, experience and prior training.

Study context

Population
Consecutive outpatients clinically suspected of SjD in a diagnostic trajectory, University Medical Center Groningen
Participants
100 consecutive outpatients
Comparison
Intraobserver and interobserver reliability of colour Doppler (CD) SGUS scoring across observers of differing experience; live vs static scoring
Outcome
Intra- and interobserver reliability of CD SGUS (OMERACT CD score 0-3 per gland; total score 0-12)
Methodological detailssingle-centre, consecutive outpatients, four independent observers, two scoring sessions, OMERACT CD scoring system
  • Single-centre
  • Consecutive outpatients
  • Four independent observers
  • Two scoring sessions
  • OMERACT CD scoring system
