Overview
Imaging detects inflammation structural damage and disease activity in rheumatologic conditions. Modalities include radiography ultrasound MRI and nuclear medicine. Imaging guides diagnosis monitoring and therapeutic decisions.
Ultrasound Role
Musculoskeletal ultrasound identifies synovitis tenosynovitis and erosions in real time. Power Doppler assesses active inflammation and response to therapy. It supports targeted injections and monitoring.
MRI Applications
MRI visualizes early inflammatory changes bone marrow edema and soft tissue involvement. It is sensitive for sacroiliitis and axial disease assessment. Quantitative MRI metrics are under investigation for monitoring.
Imaging Biomarkers
Imaging biomarkers quantify disease activity and structural progression for trials and clinical care. Standardized scoring systems improve comparability across studies. Integration with clinical indices enhances patient management.
