Radiographic Parameters in Predicting Outcome of Patients with Hepatocellular Carcinoma Treated with Yttrium-90 Microsphere Radioembolization
Figure 1
An 89-year-old man with hepatocellular carcinoma involving liver segment VI. (a) Before selective internal radiotherapy (SIRT), the tumor (10.2 cm) had poorly defined margins and peripheral enhancement. (b) After SIRT, the tumor had increased size (12.9 cm), increased necrosis, decreased vascularity, and decreased attenuation. This tumor was rated as progressive disease by RECIST 1.1 but favorable response by MASS criteria.
