Abstract
Abstract Muscle magnetic resonance imaging (MRI) and ultrasound (US) are emerging tools to assist in the diagnosis of children with genetic muscle disease. Increasing number of studies demonstrate that these imaging techniques can identify selective patterns of muscle atrophy, fatty degeneration, and muscle edema that help to distinguish between different early-onset genetic myopathies and muscular dystrophies. Recognizing patterns of pathology by muscle imaging can help to guide genetic testing and avoid the more invasive procedure of a muscle biopsy. Conversely, since massive parallel sequencing is now more commonly used as the initial step in diagnostic testing, imaging techniques can help to confirm or exclude if a variant of uncertain significance is indeed disease causing and compatible with a pattern of pathology as detected by muscle imaging. Whereas for diagnostic purposes and pattern recognition, muscle pathology does not need to be quantified, measuring disease progression is increasingly supported by quantitative muscle imaging, which is critical given the recent increment in rare disease therapeutic trials. Here, we discuss the value of muscle imaging techniques in pediatric muscle disease and summarize data identifying specific patterns of involvement in muscle MRI and US in some of the more common genetic myopathies and muscular dystrophies.

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 it
