Fig. 3From: Feasibility of PET/CT system performance harmonisation for quantitative multicentre 89Zr studiesRC curves derived from the 89Zr phantom experiments using SUVmean (a), SUVmax (b) and SUVpeak (c) quantitative metrics and corresponding RC curves derived from the EARL [18F]FDG phantom experiments using SUVmean (d), SUVmax (e) and SUVpeak (f) quantitative metrics. Current EARL specifications for [18F]FDG-PET/CT accreditation are presented as bold dashed lines. Systems 1–2 and 3–4 represent GE scanners Discovery 690 and Discovery 710, respectively; systems 5–6 are Siemens Biograph 40_mCT and Somatom Definition AS_mCT; system 7 is the Philips Ingenuity TF PET/CT; system 8 is the Siemens Biograph 64_mCTBack to article page
