Changes in the appearance of venous sinuses after treatment of disordered intracranial pressure
Bibliographic record
Abstract
Cerebral angiographic findings in idiopathic intracranial hypertension (IIH) and spontaneous intracranial hypotension (SIH) have been described. Conventional cerebral venography has demonstrated tapered stenoses and filling defects in the transverse sinuses of patients with IIH.1 These stenoses have also been found in >90% of IIH patients imaged with auto-triggered elliptic-centric-ordered three-dimensional gadolinium-enhanced MR venography (ATECO MRV).2 Conventional cerebral angiography demonstrated prominence of intracranial venous structures in patients with SIH.3 To date, MRI correlates of these dilated venous channels have not been described. This report discusses the use of ATECO MRV to demonstrate the normalization of venous sinus caliber associated with the resolution of these two disorders of intracranial pressure (ICP). ### Case 1. A 21-year-old woman was diagnosed with IIH. CSF opening pressure was 32.5 cm H2O. Months later, she was admitted to our institution with persistent headache and blurred vision despite maximal doses of acetazolamide. Examination revealed an obese woman with bilateral papilledema. CSF opening pressure remained elevated at 24 cm H2O. An MRI …

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.
