Figure 5. 44-year-old woman with hepatic haemangioma. (a) Grey scale fundamental ultrasound shows a hypoechoic lesion, 6.4 cm in diameter, in S7 of the liver (arrows). (b) Contrast-enhanced ultrasound images by coded harmonic imaging at 40 s after administration of Levovist. Vessels are observed around a portion of the periphery of the mass (arrows). (c) Contrast-enhanced ultrasound images acquired by 1-s intermittent transmission at 70 s after administration. The contrast is seen to be slowly filling portions of the haemangioma (arrowheads).
