Hopkins head and neck therapy assessment criteria: Neck node—axial fused PET/CT images. (A) Score 1 demonstrates no evidence of 18F-FDG–avid residual nodal disease in neck, consistent with complete metabolic response. (B) Score 2 demonstrates minimal 18F-FDG activity within left level IIA cervical lymph node, consistent with likely complete metabolic response. (C) Score 3 demonstrates mild 18F-FDG activity with right level-IIA cervical lymph node, consistent with probable postradiation inflammatory changes. (D) Score 4 demonstrates moderate, focal 18F-FDG activity within right level-IIB cervical lymph node, consistent with likely residual nodal neck disease. (E) Score 5 demonstrates intense, focal 18F-FDG activity within left level-III cervical lymph node, consistent with residual neck nodal disease. Arrows point to where original nodal metastasis was before treatment and degree of 18F-FDG uptake in posttherapy scans.
