Figure 5 Sixty-two-year old female with LR 5 hepatocellular carcinoma within segment 4a of the liver, demonstrating arterial phase hyperenhancement (APHE) (A) and “washout” (B); 3 mo post transarterial radioembolization (TARE) there is persistent arterial phase nodular enhancement (arrow) (C) with associated “washout” on portal venous phase (D) within the largely necrotic treatment cavity, LR TR Equivocal; 6 mo post-TARE, the treatment cavity decreases in size and the nodular area of APHE is no longer identified on arterial phase (E) and portal venous phase (F), LR TR Nonviable; geographic APHE in the surrounding parenchyma is compatible with post-radiation changes (E and F).
