A century in the making: Medical imaging, nuclear medicine, and the transformation of global healthcare
Bibliographic record
Abstract
This paper explores how the global mobility of healthcare professionals shapes the evolution of nuclear medicine through shifts in labour, logistics, and knowledge systems. It examines how credentialing asymmetries, fragile supply infrastructures, and uneven digital integration affect equitable access to innovation and practice. The analysis highlights how professional circulation generates both collaboration and structural exclusion, particularly when expertise crosses regulatory and institutional boundaries. It argues that mobility not only redistributes clinical skills but also redefines authority, standards, and epistemologies in medical imaging. By tracing these dynamics, the paper opens space for rethinking inclusion, accountability, and fairness in the global development of medical imaging and nuclear medicine.

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.
