Acute examination to rule out cervical spine injuries in adults
Bibliographic record
Abstract
This paper provides a brief overview of current information and recommendations regard-ing acute imaging of adult patients to rule out cervical spine injuries. It summarizes the possibilities of plain X-ray examination of the cervical spine, which is technically demand-ing and has low diagnostic yield. Therefore, it is no longer recommended. Exceptions are locations where CT is not available and patients for whom exposure to medium or high doses of ionizing radiation is contraindicated. Routinely performed CT examinations of the cervical spine to rule out injury have a significant medical and financial impact. For this reason, internationally recognized criteria sets NEXUS (National Emergency X-Radiography Utilization Study) and CCR (Canadian C-spine Rule) have been introduced. These include information from the patient's history and clinical examination and are used to indicate the need for cervical spine CT to exclude trauma. Both systems are described and compared. According to some recommendations and in the opinion of the authors, combining the two systems could further improve their effectiveness.

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.
