Abstract
Diagnostic imaging plays a crucial frontline role in healthcare, providing the information some physicians need to make a diagnosis and determine a course of treatment for their patients. However, wait times for access to diagnostic imaging examinations continue to be long. This is due to a number of factors, including the expanding indications for CT and MRI and growing reliance on imaging studies, Canada's lag in purchasing new equipment, an American influence on the Canadian healthcare system and clinicians' requests for inappropriate examinations. A number of strategies need to be implemented to maximize radiology's efficiency and ensure that services are being used appropriately. The author advocates the use of appropriateness guidelines for referring physicians, delisting tests that are completely inappropriate, implementing the use of radiology information systems, enhancing radiologist efficiency and using physician extenders to perform less complex medical work.

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.
