Evaluation of Optimal Acquisition Duration or Injected Activity for Pediatric ¹⁸F-FDG PET/CT

Abstract

Evaluation of image volumes generated from simulated shorter acquisition durations suggests that imaging times for larger patients (>22 kg) can be reduced from 5 min/FOV to 3 min/FOV without a loss of diagnostic utility. Using decreased acquisition times as a surrogate for (18)F-FDG dose, (18)F-FDG dose can be reduced by approximately 40% when all patients were scanned for 5 min/FOV.
