18F-FDG PET/CT of patient with no evidence of malignancy after PDT. (A) Native CT image shows discrete hypodense areas in liver segments 4B and 5. (B) Fused image (CT, 50%; PET, 50%) enables anatomic correlation of glucose metabolism. (C) 18F-FDG PET image shows 75% and 100% isocontour areas used for SUV analysis (SUVmax = 3.2 and SUV75% = 2.5). Note atrophy of left liver lobe.

18F-FDG PET/CT of patient with residual Klatskin’s tumor after PDT and Yamakawa stent implantation. (A) Native CT image shows large hypodense area in liver hilus. (B) Fused image (CT, 50%; PET, 50%) enables anatomic correlation of increased glucose metabolism. (C) 18F-FDG PET image shows 75% and 100% isocontour areas used for SUV analysis (SUVmax, 5.0, and SUV75%, 4.1).
