Fig. 2From: Characterization of focal liver lesions using sulphur hexafluoride (SF6) microbubble contrast-enhanced ultrasonographyA 59-year-old female, HCV + ve with elevated AFP serum level (340 ng/ml) and accidentally discovered HFL on routine US check-up. Triphasic CT examination reveals a left lobe exophytic lesion with arterial phase enhancement followed by washout in the porto-venous and delayed phases. a NEUS revealed an exophytic hypoechoic focal lesion. b–d CEUS real-time examination during early arterial, portal, and late phases showed early homogenous arterial contrast uptake with rapid washout to appear hypoechoic in late phase, consistent with HCCBack to article page
