Calcium Pyrophosphate Crystals Detected by Ultrasound in Patients without Radiographic Evidence of Cartilage Calcifications: Figure 1A-B.
Bibliographic record
Abstract
There is a consistent body of evidence supporting the role of ultrasound in patients with rheumatoid arthritis (RA)1,2. More recently, ultrasound is gaining interest among rheumatologists for the assessment of calcium pyrophosphate dihydrate (CPPD) disease3,4,5, because it has demonstrated high specificity in the detection of pathological findings indicative of pyrophosphate crystal deposits6,7,8. The definite diagnosis of CPPD disease requires identification of CPPD crystals in the synovial fluid by polarizing light microscopy. However, aspiration of the synovial fluid is not always possible for many reasons. In those cases, imaging modalities are important as surrogate diagnostic tools. We describe 2 cases showing the diagnostic potential of ultrasound in the detection of pyrophosphate crystal deposits in patients with negative radiographic evidence of cartilage calcifications. A 58-year-old woman presented to our clinic for a history of recurrent attacks of monoarthritis at right knee level, associated …

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.
