Representative PET/CT images of two patients with Hodgkin lymphoma. Representative Maximum Intensity Projection (MIP) and PET/CT fused images of baseline, interim, and end of therapy (EoT) scans. On the left (blue), the figure shows a patient which responded to treatment (Deauville score at interim, and complete metabolic response after therapy according to Lugano criteria). On the right (red), the figure presents a patient showing an initial response at interim evaluation (Deauville score 1) but classified as non-responder at the final assessment (progressive disease according to Lugano criteria).
