Figure 2. Visualization of spatial functional liver loss with SC SPECT/CT. 1st row (A-C): CP-A patient; 2nd row (D-F): CP-B patient; 1st column (A and D): radiation treatment plans with isodose lines; 2nd column (B and E): radiation treatment plans overlaid with pre-treatment SC SPECT/CT scans; 3rd column (C and F): radiation treatment plans overlaid with post-RT SC SPECT/CT scans demonstrating a higher threshold for function liver loss for the CP-A patient at 30 Gy and above (C) compared to the CP-B patient at 10 Gy and above (F). SC: Sulfur colloid; CP: child-pugh; RT: radiotherapy.
