Role of Computed Tomographic Cisternography in the Management of Cerebrospinal Fluid Rhinorrhea
Bibliographic record
Abstract
In a retrospective review of 13 patients, computed tomographic cisternography (CTC) was the primary imaging modality used for the detection of cerebrospinal fluid (CSF) leaks. In five of the cases, the diagnosis of CSF rhinorrhea was confirmed by the beta2-transferrin test. In the remaining cases, it was corroborated through endoscopic visualization, clinical history, and nuclear scanning. This study analyzes the efficacy of CTC in the detection of CSF leaks and discusses the different methods of computerized manipulation and reconstruction of the images for effective site localization. The study demonstrates that computerized reconstruction of images should be considered an integral part of CTC because it appears to be an inexpensive and simple diagnostic tool that improves on the accuracy of detection. Although T2-weighted magnetic resonance imaging may be helpful, this study emphasizes the efficacy of CTC in the diagnosis of CSF leaks. Using the techniques of image reconstruction improves on diagnostic precision with relatively little increase in cost, time, and labour. This study also introduces a diagnostic algorithm for otolaryngologists dealing with the challenge of identifying and locating CSF leaks.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
