Imaging features in psoriatic arthritis
Bibliographic record
Abstract
Psoriatic arthritis (PsA) is characterized by a diverse array of musculoskeletal pathology involving the joints and peri-articular structures in both the peripheral and axial skeleton. For a long time, PsA was not recognized as a specific entity but was rather considered a subtype of rheumatoid arthritis that occurred in combination with skin psoriasis and even was considered to be a mild disease with a benign course. Therefore, research in PsA has long been behind rheumatoid arthritis in terms of not only diagnosis, prognosis and treatment but also imaging. The clinical spectrum of PsA is very diverse, involving the spine, sacroiliac joints, peripheral joints and/or entheses. PsA is characterized by entheseal pathology, usually in the context of a present or past history of psoriasis. Other manifestations are small joint polysynovitis and diffuse osteitis closely linked to enthesitis. Damage of these structures and disease activity can be imaged using a variety of modalities, including conventional radiography, ultrasonography and MRI.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
