Image quality assessment along the one metre axial field-of-view of the total-body Biograph Vision Quadra PET/CT system for 18 F-FDG.

Image noise increases substantially towards the ends of the aFOV. However, good IQ in compliance with generally accepted benchmarks is achievable for an aFOV of > 90 cm. When accepting higher image noise or using dedicated protocol settings such as stronger filtering a useful aFOV of around 1 m can be achieved for a 2 min acquisition time.
