In the low Ki-67 expression group, FT and PE in the arterial phase showed no significant difference between the HCC lesions (16.7 ± 25.1 s, 1.1 × 108 ± 9.7 × 107 a.u, respectively) and the distal liver parenchyma (4.7 ± 34.9 s, 1.1 × 108 ± 9.4 × 107 a.u, respectively) (p = 0.104, p = 0.773, respectively). The gene discussed is MKI67; the disease is hepatocellular carcinoma.
