FDG-PET/CT images of a patient with proven breast cancer. a Axial PET image, standard-voxels. b Axial-fused PET/CT image, standard-voxels. c Axial PET image, small-voxels. d Axial-fused PET/CT image, small-voxels. SUVmax for this small lymph node (red arrows) increased from 2.1 on standard-voxel PET with visual score benign to SUVmax 3.3 on small-voxel PET and visual score malignant. On follow-up imaging after chemotherapy, this lymph node showed regression, which indicated that the lymph node was malignant. This confirmed the small-voxel score and the classification using the optimal SUVmax cut-off
