MRI Protocol for the Assessment of Juvenile Idiopathic Arthritis of the Wrist: Recommendations from the OMERACT MRI in JIA Working Group and Health-e-Child
Bibliographic record
Abstract
To the Editor: Magnetic resonance imaging (MRI) is the only imaging tool that allows us to assess all relevant structures in juvenile idiopathic arthritis (JIA): the synovium, cartilage, bone, ligaments, and tendon sheaths. The interpretation of the MRI of the wrist in patients with JIA is challenging because of the complex anatomy and the presence of normal variants mimicking pathology1,2. There is a need for a consensus of MRI interpretation in children with JIA and a universal protocol for MRI acquisition, which can enable uniformity of identification of all involved structures. From 2012 onward, an international collaborative network of clinical and radiological experts on imaging in JIA has set out to standardize the challenging MRI acquisition and interpretation of JIA … Address correspondence to Dr. C.M.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
