FIGURE 1. Pretherapy (A) and follow-up posttherapy (B) PET scans of patient with Burkitt's lymphoma involving multiple vertebrae (arrows). Follow-up scan demonstrates diffuse bone marrow uptake secondary to administration of growth factor, with decreased uptake seen in areas of previous bone marrow involvement.

FIGURE 3. Pretherapy (A) and posttherapy (B and C) PET scans (left) and CT scans (right) of patient with diffuse large B-cell lymphoma and large anterior mediastinal/right pericardial mass. Pretherapy scan shows intense 18F-FDG uptake. One follow-up scan (B) demonstrates shrinkage of mass but persistent uptake. Biopsy was negative for malignant cells. A later follow-up scan (C) demonstrates growth of residual 18F-FDGavid mass.
