Diseases of the Sella Turcica and Parasellar Region
Bibliographic record
Abstract
Abstract Knowledge of the anatomy in the regions of the sella turcica, suprasellar cistern, and cavernous sinus paired with clinical history and presentation is important for accurate image interpretation. Focused diagnosis of lesions in these regions requires identifying the anatomic location in which a lesion arises, evaluation of specific imaging findings inherent to the lesion as well as in the surrounding structures, and correlation with clinical presentation (symptoms and signs). It is important to determine whether a mass arises in the sella turcica versus the suprasellar cistern, and whether it involves both the sella turcica and suprasellar cistern. Imaging features of a sellar mass that should be assessed include: Arising from or separate from the pituitary gland Cystic degeneration Size of the sella Infundibulum involved Stalk deviation Relationship to chiasm Edema optic pathways, hypothalamus Cavernous sinus—internal carotid artery Osseous remodeling, destruction

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.
