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

Figure 3 Puncture biopsy confirmed intrahepatic cholangiocarcinoma in a 52-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 1609 × 10^-3 mm²/second, 143.89 × 10^-3 mm²/second, 1.630 × 10^-3 mm²/second, 134.59 × 10^-3 mm²/second, 552.6 × 10^-3 mm²/second, 2.064 × 10^-3 mm²/second, respectively.
