ROC curves for lymph node characterization using SUVmax and TBratio, measured on standard- and small-voxel PET images. AUCs for SUVmax were 0.93 (95% CI 0.90–0.97) and 0.93 (95% CI 0.90–0.96) for standard- and small-voxels, respectively (p = 0.71). AUCs for TBratio were 0.88 (95% CI 0.84–0.93) and 0.87 (95% CI 0.82–0.92) for standard- and small-voxels respectively (p = 0.61). AUCs for SUVmax were significantly higher as compared to AUCs for TBratio, for both standard- and small-voxels (p = 0.003 and p = 0.002)
