Evaluating microvascular invasion in hepatitis B virus-related hepatocellular carcinoma based on contrast-enhanced computed tomography radiomics and clinicoradiological factors

Figure 3 Two cases to show representative clinicoradiological factors of microvascular invasion-negative and microvascular invasion-positive hepatocellular carcinoma. A: A 63-year-old man presented with a 4.0 cm solid mass in the right lobe of the liver, featuring a peritumoral hypointensity ring (orange arrow) and smooth tumor margin; B: A 46-year-old man presented with a 15 cm solid mass in the right lobe of the liver, featuring a non-smooth tumor margin and the absence of a peritumoral hypointensity ring (yellow arrow).
