Hepatocellular carcinoma: Can LI-RADS v2017 with gadoxetic-acid enhancement magnetic resonance and diffusion-weighted imaging improve diagnostic accuracy?

Figure 1 Flow diagram of the study population. HCC: Hepatocellular carcinoma; OM: Other non-hepatocellular carcinoma malignancy.

Figure 2 Pathologically confirmed hepatocellular carcinoma in a 59-year-old woman. A: A 55.8-mm hypointense mass is seen on the precontrast image; B: The image shows hyperenhancement (not rim) in the arterial phase; C: Nonperipheral “washout” and enhancing capsule in the portal venous phase; D: Hypointensity in the hepatobiliary phase; E: Restricted diffusion in diffusion-weighted imaging; F: The mass was confirmed as hepatocellular carcinoma at 200 × magnification after hematoxylin-eosin staining.

Figure 3 Pathologically confirmed intrahepatic cholangiocarcinoma in a 47-year-old man. A: A 53.2-mm hypointense mass is seen on the precontrast image; B: The image shows rim-like hyperenhancement in the arterial phase; C: Peripheral “washout” in the portal venous phase; D: Targetoid appearance in the hepatobiliary phase; and E: Target sign in diffusion-weighted imaging; F: The mass was confirmed as intrahepatic cholangiocarcinoma at 200 × magnification after hematoxylin-eosin staining.
