Does Tumour Contrast Retention on CT Immediately Post Chemoembolization Predict Tumour Metabolic Response on FDG-PET in Patients with Hepatic Metastases from Colorectal Cancer?

Figure 2

(a, b) The column on the left demonstrates post embolization contrast retention on CT (arrows). The PET-CT images on the right demonstrates corresponding hypometabolic areas. Findings are in keeping with significant overlap. (c) The CT on the left was obtained after DEBIRI treatment to the left lobe of the liver. The middle CT demonstrates contrast retention after the DEBIRI treatment to the right lobe of the liver. There is no corresponding hypometabolic area on PET-CT. Findings would be in keeping with a “no match.”
