Table 3 Results of subjective PET image quality ratings for different reconstruction algorithms in a subanalysis for patients with high-dose (≥ 2.0 MBq/kg (n = 20 patients of study group)) and low-dose (≤ 2.0 MBq/kg (n = 25 patients of study group)) injection regimen of 18F-FDG. Italicized numbers are the reconstructed datasets yielding the highest score for each assessed parameter
