Fig. 3From: Data-driven gated PET/CT: implications for lesion segmentation and quantitationSUVmax ratios relative to baseline PET/CT. The ratios for each PET/CT method are plotted in increasing order based on the value for PET/ACT, but separated into two groups with baseline lesion mean HU > 0 on the left (#1–38) and baseline lesion mean HU < 0 on the right (#42–94)Back to article page
