Select the most avid residual lesion's uptake relative to the reference regions (mediastinal blood pool and liver) to get the Deauville score and its usual interpretation. Context (interim vs end-of-treatment, trial setting) determines whether a score of 3 counts as a complete metabolic response — see Lymphoma.

Deauville 5-point score

1 = no uptake · 2 = ≤ mediastinum · 3 = > mediastinum but ≤ liver · 4 = moderately > liver · 5 = markedly > liver (>~2×) and/or new lesions. Interim 1–3 is favourable; a Deauville 4 with a large interim ΔSUVmax (>66%) may still indicate response (per PET-adapted trials). At end-of-treatment, 1–3 = complete metabolic response, 4–5 = residual disease. Integrate with the full study and clinical context.
