Figure 4 Post-operative magnetic resonance imaging of case 2 (6 months). A: Diffusion-weighted phase revealed no obvious tumor activity in the residual liver; B and C: T1-weighted enhanced magnetic resonance imaging showed extensive tumor necrosis in the caudate lobe, and local slight enhancement around the tumor showing high signal in arterial phase and venous phase; D: Coronal delayed phase confirmed extensive tumor necrosis in the caudate lobe with marginal local slight enhancement (arrow) and no tumor activity in the remaining right liver.
