Radiomics signature: A potential biomarker for β-arrestin1 phosphorylation prediction in hepatocellular carcinoma

Figure 3 Representative images of contrast-enhanced computed tomography and β-Arrestin1 phosphorylation (magnification, × 100). A: CT images of a 45-year-old man with a 6.3-cm hepatocellular carcinoma (HCC) in the right liver lobe in the plain phase; B: The tumor shows heterogeneous hyperenhancement in the arterial phase; C: The tumor shows washout at the portal venous phase with intratumor necrosis, an ill-defined capsule and a non-smooth tumor margin. D: Immunohistochemical staining shows a β-arrestin1 phosphorylation-negative status at 100× magnification.
