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

ABSTRACT:

Aim

Recently, total-body PET/CT systems with an extended axial field-of-view (aFOV) became commercially available which allow acquiring physiologic information of multiple organs simultaneously. However, the nominal aFOV may clinically not be used effectively due to the inherently reduced sensitivity at the distal ends of the aFOV. The aim of this study was to assess the extent of the useful aFOV of the Biograph Vision Quadra PET/CT system.

Methods

A NEMA image quality (IQ) phantom mimicking a standard [¹⁸F]FDG examination was used. Image contrast and noise were assessed across the 106 cm aFOV of the Biograph Vision Quadra PET/CT system (Siemens Healthineers). Phantom acquisitions were performed at different axial positions. PET data were rebinned to simulate diff
