The Novel OMERACT Ultrasound Scoring System for Salivary Gland Changes in Patients With Sjögren Syndrome Is Associated With Magnetic Resonance Imaging (MRI) and Salivary Flow Rates
Authors' conclusion
There is moderate to strong agreement between the OMERACT US and MRI scores for major salivary glands in patients with pSS.
Study context
- Population
- Patients with pSS who also had MRIs performed
- Participants
- 11 patients
- Exposure
- OMERACT ultrasound (US) scoring vs MRI scoring and unstimulated whole salivary flow rates (U-WSFRs)
- Outcome
- Agreement between OMERACT US and MRI scores (score ≥ 2 = gland pathology), and association between U-WSFRs and imaging structural lesions
Methodological detailsconstruct validity, semiquantitative 0-3 scoring, nine sonographers, 2 radiologists
- Construct validity
- Semiquantitative 0-3 scoring
- Nine sonographers
- 2 radiologists
