Value of intravoxel incoherent motion and diffusion kurtosis imaging to differentiate hepatocellular carcinoma and intrahepatic cholangiocarcinoma

Figure 2 Surgically confirmed moderately differentiated hepatocellular carcinoma in a 65-year-old man. A: T2-weighted imaging image; B: Diffusion-weighted image with b = 800 mm²/second; C: Pure diffusion coefficient (D) map; D: Perfusion fraction (f) map; E: Standard apparent diffusion coefficient (SADC) map; F: Pseudo diffusion coefficient (Dstar) map; G: Mean kurtosis coefficient (MK) map; H: Mean diffusion coefficient (MD) map. The mean D, f, SADC, Dstar, MK, and MD values for the tumor were 0997 × 10^-3 mm²/second, 92.62 × 10^-3 mm²/second, 1.037 × 10^-3 mm²/second, 55.18 × 10^-3 mm²/second, 651 × 10^-3 mm²/second, and 1.179 × 10^-3 mm²/second, respectively.
