Comparison of ¹⁸ F-fluorodexoyglucose positron emission tomography scan uptake in spine with sites of normal bone marrow activity on whole body white cell scan post six cycles of chemotherapy. White cell scan anterior planar view (A), White cell scan posterior planar view (C) three-dimensional maximal intensity projection (MIP) ¹⁸F-FDG PET scan images (B). The overall pattern of FDG uptake on PET scan is similar to the white cell scan uptake in keeping with sites of normal regenerating marrow rather than lymphoma. Arrows highlight similarities in FDG and white cell uptake in the thoracic and lumbar spine.
