Figure 2: The enhancement pattern of hepatic hemangioma on contrast-enhanced ultrasound images. (a) A mixed-echoic lesion is visible at S7 on the gray-scale ultrasound image, and there is an acoustic halo around the lesion. (b) After injecting contrast agent, peripheral nodular enhancement (yellow arrow) has appeared during the arterial phase. (c) Centripetal fill-in of peripheral enhancement has occurred during the portal phase. (d) The lesion still has slightly hyperenhancement compared with the liver parenchyma during the delayed phase
