FIGURE 2. WB PET images of 51-y-old woman with stage IV low-grade NHL in whom CT, FDG, and MET PET were concordant in detection of nodal findings. In FDG images (A), 2 coronal slices show intense focal uptake in multiple lymph node regions both superior and inferior to diaphragm. (B) Coronal MET PET images show similarly intense focal uptake in multiple lymph node regions. Physiologic uptake pattern differs between FDG (e.g., urinary bladder) and MET (e.g., liver, pancreas).
