The same radiographs, read two ways — a conventional report beside a RheumaView™ structured radiographic report.
Why this is a foundational case
This is deliberately one of the simplest cases — a single-date radiographic study with no prior imaging and no cross-modality input (no MRI, ultrasound, DEXA or laboratory data). What the structured report contributes even at baseline is descriptor completeness, pattern separation, mimic-control, quantified laterality and explicit data-needs. See how case complexity scales ↓.

RESEARCH SYNTHESIS
Baseline multi-region radiographs demonstrate a dominant pattern of bilateral multifocal interphalangeal osteoarthrosis with probable central erosive-remodeling component, together with moderate bilateral first CMC/triscaphe osteoarthrosis. The submitted hands, wrists and feet show no convincing radiographic evidence of established rheumatoid-type marginal erosive arthropathy, including no definite MCP marginal erosions, destructive radiocarpal/intercarpal change, carpal collapse, fixed MCP ulnar subluxation pattern, ulnar styloid erosions or definite MTP marginal erosions. Additional findings include mild bilateral hallux valgus with mild first MTP osteoarthrosis, right slightly greater than left; minimal bilateral midfoot degenerative change; mild bilateral calcaneal enthesopathic change; and mild symmetric knee osteoarthrosis. Generalized reduced mineralization appearance and bilateral distal lower-extremity arterial calcifications are present. Longitudinal change, densitometric correlation, normalized composite indices and agreement metrics are not computable from the available baseline radiographs alone.
Single-date, one modality. Bilateral peripheral radiographs read at baseline, with no priors and no cross-modality input.
Multiple timepoints contribute a baseline against which interval change in erosions, joint-space narrowing and alignment becomes computable.
More than one modality compounds the read — MRI, ultrasound, DEXA or laboratory input correlating activity, density and soft-tissue disease.
