Figure 4.

Complete response by PET/CT. (A) Post-gadolinium T1-weighted MRI shows diffuse involvement of the right hepatic lobe. (B) Post-90Y-RE Bremsstrah lung SPECT/CT scan post radioembolization shows ideal Y90 deposition. (C,D) Increased central FDG-18 uptake seen on pretreatment PET/scan (C) was no longer seen on PET/CT scan (D) obtained 3 months after radioembolization. PET, positron emission tomography; CT, computed tomography; SPECT, single-photon emission computed tomography; SUV, standardized uptake value.
