Do you know?
Increasing acquisition time improves image quality more effectively than increasing injected dose.
Physics behind it:
•Longer acquisition → more counts
•More counts → better signal-to-noise ratio
•Higher dose → ↑ radiation, not always proportional image improvement
Clinical relevance:
Optimizing scan time is often safer and smarter than increasing patient radiation dose.
