Tc-99 m-galactosyl human serum albumin scintigraphic images obtained from a 65-year-old man with genotype 2b infection before sofosbuvir/velpatasvir treatment and after sustained virologic response at 24 weeks post-treatment (SVR24). Before treatment, the planar image shows weak accumulation of radiotracer in the liver and enhanced pooling in the heart; hepatocyte receptor index (LHL15) and blood clearance index (HH15) were 0.70 and 0.78, respectively (a). After SVR24, liver accumulation of radiotracer increased and cardiac pooling decreased; LHL15 and HH15 improved to 0.85 and 0.63, respectively (b). The patient’s hepatic functional reserve improved from Child–Pugh-Turcotte grade B to grade A after SVR24
