Figure 1 Preoperative imaging. A and B: Baseline contrast-enhanced magnetic resonance imaging (MRI). Contrast-enhanced MRI demonstrated a 40 mm mass in segment IV of the liver with arterial wash-in (A) and wash-out on the portal venous phase (B) and features of cirrhosis (irregular surface, relative hypertrophy of segment I); C and D: Selective intra-tumor deposition of 90Y microspheres after first SIRT session (C) and deposition of 90Y microspheres to segments II and III after the second SIRT session (D).
