GENERAL NUCLEAR MEDICINE Outcome of Hepatobiliary Scanning in Neonatal Hepatitis Syndrome
Bibliographic record
Abstract
To evaluate the diagnostic information gained from hepatobiliary scanning in infants, we reviewed 86 consecutive infants who were s4 mo old and were treated for conjugated hyperbilirubinemia at the Hospital for Sick Children in Toronto between 1985 and 1993 and who had technetium iminodiacetic hepatobiliary scanning and a percutaneous liver biopsy performed in close temporal proximity. Methods: Retrospective reviews of hospital charts and blinded reviews of hepatobiliary scans were performed. Results: There were 58 male and 28 female infants (age range, 2-124 days; mean = 65 days). Hepatobiliary scanning failed to show biliary excretion into the gastrointestinal tract in 53 of 86 patients. Forty of these 53 had extrahepatic biliary atresia. The remaining 33 patients demonstrated biliary excretion into the gastrointestinal tract; 24 of 33 had neonatal hepatitis. Among 13 of the 53 patients who had no evidence of biliary excretion and who also did not have extrahepatic biliary

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.
