Abstract
OBJECTIVE: The aim of the study was to evaluate whether maximum intensity projection (MIP) images improve the detection and the delineation of the anatomic makeup of pulmonary nodules and/or arteriovenous malformations (pAVMs) in children with hereditary hemorrhagic telangiectasia (HHT). MATERIALS AND METHODS: Two radiologists (D.M., E.I.C.) performed a blinded review of chest multidetector computed tomography scans in 39 children (age, 0-18 years) with proven HHT. Multiplanar 2.5 mm slices were blindly compared with multiplanar MIP for the presence of nodules and/or overt pAVMs and for the ability to identify vessels associated with the pAVMs. Parameters that were assessed included number of definitive nodules, number of definitive pAVMs, and the ability to detect the feeding artery or draining vein in both conventional and MIP images. RESULTS: Our study showed similar detection rates between axial scans and MIP images for the detection of nodules (axial R1: 75 vs 62, P = 0.05; MIPS: 78 vs 86, P = 0.05) and in the determination of definite pAVMS (axials: 21 vs 29, P = 0.0007; MIPS: 27 vs 35, P = 0.01). Statistically significant differences were obtained in the ability to identify the feeding artery and draining vein between standard 2.5 mm slices and MIP images (axials: 13 vs 13, P = 0.0008; MIPS: 27 vs 23, P = 0.01). No other data parameters achieved statistically significance. CONCLUSIONS: Maximum intensity projection images in children with HHT can help identify the presence and the anatomy of pAVMs for future embolization.

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
