Harmonisation of standard uptake values in long-axial field-of-view PET/CT: an exploratory study

The study proposes a detector-splitting phantom scanning strategy as a practical framework for robust SUV harmonisation for LAFOV PET systems. Position-specific or jointly optimized harmonisation filters applicable across all axial detector positions may be beneficial for ensuring reliable and comparable SUV measurements, particularly in longitudinal follow-up and multi-scanner clinical settings.
