Abstract

fetched live from OpenAlex

Treatment response in Cystic Fibrosis (CF) is traditionally monitored using pulmonary function tests (PFTs), such as spirometry. However, PFTs can be insensitive to treatment, particularly in early CF lung disease [1]. Hyperpolarized (HP) 129Xe MRI (Xe-MRI) has been shown to be feasible in children [2], more sensitive to early CF lung disease compared to PFTs [3 and captures improvements in ventilation inhomogeneity in pediatric CF patients receiving intravenous antibiotic treatment for a PEx [4]. However, access to hyperpolarized 129Xe gas is not widely available and Xe-MRI requires subjects to perform an extended breath-hold (10–15 s), which is challenging for very sick children.

Full frame distilled prediction

Teacher imitation

Not 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.
