  1. For malignant lymph nodes, the small-voxel score was more often correct as compared to the standard-voxel score (p < 0.001), while for benign lymph nodes, the standard-voxel score was more often correct (p = 0.04). Across all lymph nodes visualised on PET/CT, accuracies of standard- and small-voxel scores were comparable (p = 0.13)
