Fig. 4From: Standardisation of conventional and advanced iterative reconstruction methods for Gallium-68 multi-centre PET-CT trialsAverage CRCmax (left), CRCmean (middle) and CRCpeak (right) for all 6 Gallium-68 (blue curve) and the 12 Fluorine-18 (red curve) acquisitions reconstructed with standard OSEM. The error bars represent the standard deviation between sites. Significant difference was noticed for the 13-mm sphere at the 5% significance level for CRCmax and CRCpeakBack to article page
