The share of corresponding/leading authors in scientific publications in Radiology, Nuclear Medicine, and Imaging in Canada is projected to slightly decrease from 90.08% in 2024 to 89.01% in 2028. This gradual decline suggests a modest shift in the distribution of authorship roles over the five-year period.

Between 2024 and 2025, a marginal reduction of 0.3% is expected. A consistent downward trend continues with annual decreases of 0.27% between subsequent years. The Compound Annual Growth Rate (CAGR) over this period indicates an average annual decrease of approximately 0.3%.

Future Trends to Watch For:

Collaboration Dynamics: Increased collaborations might lead to a more even distribution of lead author roles.
Technological Advancements: Advances in AI and digital tools could influence the author distribution by promoting interdisciplinary research.
Policy Changes: Adjustments in publication policies or recognition systems may impact the dynamics of authorship roles.
