Figure 18  LR-5 observation. A and B: Axial T2 weighted (A) and volumetric interpolated breath-hold examination (B) show a segment VI observation with high signal intensity (arrows); C and D: On arterial phase (C) strong enhancement is seen, better depicted on subtracted image (D); E: On portal phase washout is seen categorized as LR-5; F: Unenhanced computed tomography scan after TACE shows accumulation of iodized oil (arrow) within the tumor; G and H: However on post-contrast follow up magnetic resonance imaging on arterial phase (G) there is residual nodular enhancement within a lesion clearly depicted on subtracted image (H) categorized as LR-treatment response viable.
