Imaging blunt traumatic aortic injury: a Canadian tertiary care trauma centre case series
Bibliographic record
Abstract
Few individuals survive blunt traumatic aortic injury (TAI); however, the mortality rate is dramatically lowered by timely diagnosis and treatment. We performed a retrospective review of patients that had undergone aortography or were entered in a trauma database with a diagnosis of TAI between December 1, 1996, and April 1, 2004. The diagnostic utility of computed tomography (CT) was compared to the gold standards of aortography and operative findings. Forty charts were reviewed. Fifty-two percent had indirect CT signs and 39 percent had direct CT signs of TAI. Six TAI's were surgically confirmed and repaired. Computed tomography for TAI had a sensitivity of 100 percent and a specificity of 74 percent. Computed tomography imaging has obviated aortography in screening for TAI. Aortography continues to have a valuable diagnostic role prior to surgical management.

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.
