Nomogram prediction of vessels encapsulating tumor clusters in small hepatocellular carcinoma ≤ 3 cm based on enhanced magnetic resonance imaging

Figure 5 Representative images of qualitative gadopentetate dimeglumine-enhanced magnetic resonance imaging features for early recurrence in small hepatocellular carcinoma patients with actual and predicted vessels encapsulating tumor clusters positivity. A: In a 49-year-old man with a tumor size of 1.9 cm, T2-weighted imaging showed that the tumor had irregular shape and non-smooth margin; B: Intratumoral non-rim homogeneous hyperenhancement in the arterial phase; C: In the portal phase, there was an enhanced signal with a volcanic shape observed around the tumor; D: The enhancement within the tumor exhibited rapid washout and relatively low signals in the delayed phase.
