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

ABSTRACT:

Purpose

SUV harmonisation was proposed to reduce discrepancies in SUV measurements and ensure SUV comparability across different PET scanners. A SUV harmonisation protocol has been established based on short-axial field-of-view (SAFOV) PET. However, long-axial field-of-view (LAFOV) PET features a different scanning mode and clinical workflow compared with SAFOV PET, and no dedicated SUV harmonisation protocol has yet been developed. This study aimed to perform an exploratory investigation of SUV harmonisation on LAFOV PET.

Methods

The long-axial detector was divided into five segments based on typical patient anatomical positioning. A NEMA IEC body phantom filled with ¹⁸F-FDG solution was sequentially scanned at each detector position. SUV harmonisation was perfor
