The description of enhanced CT of intrahepatic hemangioma is as follows: firstly, describe the plain scan performance, enhanced performance, and compare the two; secondly, the plain scan performance is generally round or oval, low density, clear boundary, uniform density, large hemangioma is usually above 4 cm, and more low density area is visible in the center of the tumor foci as fissure, stellate or irregular; then, the enhanced CT performance is mainly high density enhancement at the edge of the lesion in early stage, enhanced The area progressively expands toward the center of the lesion for a long time, and the delayed scan shows isointense filling of the lesion with isointense duration of 10-15 minutes. The enhancement of small hemangioma lesions is not significant, and the arterial phase is lower than the density of the liver, and the delayed phase continues to strengthen with isointense filling without fissured low-density areas.
