(A and C) Negative 18F-FDG PET and 18F-FDG PET/CT findings for neck nodes, with visual analysis demonstrating 18F-FDG uptake in left level IIA lymph nodes equal to or less than 18F-FDG uptake in adjacent blood vessels. SUVmax was 1.1. (B and D) Positive 18F-FDG PET and 18F-FDG PET/CT findings for neck nodes, with visual analysis demonstrating 18F-FDG uptake in right level IIA lymph node greater than 18F-FDG uptake in adjacent blood vessels. SUVmax was 3.4.
