Table 1 Mean values of ΔSUVmax, ΔSUVmean, and ΔCRC (contrast recovery coefficient) averaged over the 5 acquisition times and all detected spheres (n = 14), between BPL with different β parameter and OSEM reconstructions

From: Impact of the Bayesian penalized likelihood algorithm (Q.Clear®) in comparison with the OSEM reconstruction on low contrast PET hypoxic images
