Prevalence and Characteristics of Morphometric Vertebral Fractures in the Spanish Population: Data from the OsteoSER Study
Background/Purpose: Most vertebral fractures (VFs) are asymptomatic. Vertebral Fracture Assessment (VFA) using DXA is a low-radiation method to detect morphometric vertebral fractures (MVFs). This study…Abstract Number: 1953 • ACR Convergence 2025
Machine Learning-Based Classification of Raynaud’s Phenomenon and Autoimmune Diseases in Indeterminate Capillaroscopic Patterns
Background/Purpose: Artificial intelligence (AI) has increasingly been integrated into the analysis of nailfold capillaroscopy (NFC), offering new opportunities to automate image interpretation and enhance diagnostic…Abstract Number: 1710 • ACR Convergence 2025
Defining sonographic enthesitis in psoriatic arthritis: Developing a data- and expert-driven definition for inflammatory enthesitis at the single enthesis level
Background/Purpose: Enthesitis affects 30–40% of PsA patients but remains difficult to diagnose due to overlap with non-specific entheseal pain. While OMERACT has standardized ultrasound (US)…Abstract Number: 1239 • ACR Convergence 2025
JAK inhibition appears to alter clinical and neurobiological markers of nociplastic pain in rheumatoid arthritis: a 7T MRI Brain study
Background/Purpose: Pain remains a prevalent and highly impactful issue for people with rheumatoid arthritis (RA). Among modern day targeted therapies, the janus kinase (JAK) inhibitors…Abstract Number: 0878 • ACR Convergence 2025
