Prediction of histology by B-mode and PD-mode ultrasound across different joint locations and diseases

Correspondence to Dr Raphael Micheroli; raphael.micheroli@usz.ch A few studies have investigated the predictive value of ultrasound (US) regarding specific histological findings and no study so far assessed the respective impact of different joint locations and diseases.1–3 Thus, the aim of this study was to investigate whether US—using grey scale (B)-mode and power Doppler (PD)-mode—can predict synovial characteristics in patients with specific inflammatory rheumatic diseases across different joint locations. [...]PsA was related to significantly higher vascularisation in the multivariable model (estimate 3.27; 95% CI 0.19 to 6.36; p=0.039), a finding previously described.9 A multinomial logistic regression model using B-mode US as independent variable showed a high likelihood ratio for prediction of pathotype (LRT 11.76, p
