Answer

Positron emission tomography (PET)/CT scanning has largely supplanted gallium-67 (67 Ga) scanning and is highly recommended for patients with non-Hodgkin lymphoma. [47, 48, 49, 50, 51]

Many lymphomas are 2-[fluorine-18]fluoro-2-deoxy-d-glucose (FDG) avid; their response to treatment can be assessed by using this modality. Occult sites of disease may also be identified on PET/CT scans. Many newer "response-based" chemotherapy protocols use PET scanning to assess response and guide subsequent treatments.
