Figure 1. Positron emission tomography/computed tomography (PET/CT) for restaging of recurrent non-Hodgkin's lymphoma (NHL): (a) whole body maximal intensity projection (MIP) PET; (b) transaxial PET; (c) fused PET/CT; and (d) transaxial CT images. The MIP image shows multiple foci of FDG uptake above and below the diaphragm. Linear activity is demonstrated in the left abdomen (solid arrow). Transaxial PET/CT images at the level of the mid-abdomen localize the finding to a distended left ureter (+).
