Radioembolisation and portal vein embolization before resection of large hepatocellular carcinoma

Figure 1 Tumor evolution throughout the therapeutic sequence. A: Contrast-enhanced computed tomography (CT) scan at presentation showing, in portal phase, a 167 mm tumor in segment VIII with features of hepatocellular carcinoma; B: Yttrium-90 (⁹⁰Y) positron emission tomography (PET)-CT performed 12 hours after transarterial radioembolization (TARE). Images are displayed in orthogonal views, centered on the liver tumor. Upper row: CT scan without contrast. Middle row: ⁹⁰Y emission PET images showing high and selective accumulation of ⁹⁰Y microspheres in the tumor site. Lower row: fused ⁹⁰Y PET-CT images; C: Contrast-enhanced CT scan 17 wk after TARE and 6 wk after portal vein embolization showing, in portal phase, a 50% tumor volume reduction and hypertrophy of the future remnant left liver.
