Abstract
In Reply Thank you for your interest in our cerebellopontine angle lipoma case report. You are correct that either CT or MR can be used to diagnose lipomas. Both are not required. Lipomas have a negative Hounsfield unit measure on CT. On MR, lipomas are T1 hyperintense, T2 variable intensity but usually hyperintense, do not enhance following contrast, and demonstrate signal loss on both T1 and T2 with fat saturation. You are correct that using fat saturation on the postcontrast T1 sequences is more convenient for assessing enhancement. However, careful expert comparison of corresponding slices in multiple planes of the precontrast T1 sequences without fat saturation to the postcontrast T1 sequences without fat saturation can also exclude enhancement.

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.
