A novel use for myocardial perfusion scans: diagnosis of bile duct injury
Bibliographic record
Abstract
A 69-year-old woman was admitted to a tertiary care centre after suffering from an iatrogenic bile duct injury, diagnosed by the unexpected leakage of bile during laparotomy for a colectomy. On initial assessment the patient was clinically stable, although she remained intubated after her surgery. In order to diagnose whether or not she sustained a complete or partial bile duct injury, a finding that would determine if she underwent conservative management or surgical repair, a technetium-99m-hepatobiliary scan was requested. Owing to a shortage in technetium-99m-iminodiacetic acids, the radiopharmaceutical (tracer) for this imaging test, a decision was made to employ technetium-99m-tetrofosmin, the tracer for cardiac scans (traditionally used for diagnosis of myocardial perfusion) as it has been established that this tracer is excreted in the biliary tract. The imaging showed flow of bile into the bowel, thereby establishing bile duct continuity and permitting conservative 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.
