Figure 1. — A. Axial PET/CT image demonstrates bilobar FDG-avid hepatic metastases in a 57-year-old woman with liver-dominant metastatic breast cancer. The patient was treated with radioembolization, starting with the right lobe. B. Immediate post-procedure SPECT/CT demonstrates preferential tumoral uptake of yttrium-90. C. PET/CT images were loaded into Hermes software, and the liver (yellow line) and tumors (red line) were contoured. In this case, an estimated 212 Gy was delivered to tumor, whereas 72 Gy was delivered to nontumoral parenchyma. D. Follow-up PET/CTdemonstrates complete response in right hepatic tumors, with interval progression of the untreated left lobe tumors.
