Hepatic hemangioma and hepatocellular carcinoma can be differentiated by ultrasound, enhanced CT or abdominal enhancement MRI. 1. Ultrasound: Ultrasound examination shows that hepatic hemangioma is mostly hyperechoic, with uniform tumor body, single density, indicating smooth and clear border, and the blood flow is round and stable. Hepatocellular carcinoma shows hypoechoic or very hypoechoic with irregular morphology and obvious satellite foci, and the phenomenon of pseudo-footing with richer blood flow can be found; 2. Enhanced CT: When doing enhanced CT scan, the enhancement of hepatic hemangioma is characterized by fast in and slow out, that is, node-like enhancement can be seen at the early edges, and as time progresses, the enhancement gradually progresses and spreads to the central area, and the delayed scanned lesions are filled with equal density. Larger lesions may show no significant enhancement in the central hypodense area. Enhanced CT of hepatocellular carcinoma may show that the signal intensity after contrast injection is more obvious and faster than that of hepatic hemangioma, with longer dwell time, and the enhancement is fast in and fast out. In contrast, when dynamic enhancement scan is performed for hepatocellular carcinoma, the lesions in the arterial phase are mildly unevenly intensified, and in the portal vein phase and equilibrium phase they show isointense or low signal.
