B-Flow contrast US with Levovist in hepatic tumors: preliminary results.

Usefulness of Levovist contrast ultrasonography by the B-Flow method was evaluated in cases of hepatic tumor. Subjects included 14 patients with moderately differentiated hepatocellular carcinoma and 4 patients with hepatic hemangioma. Each patients had a single tumor mass. Images showed strong staining in 11 of the 14 nodes in the hepatocellular carcinomas and all 4 hemangiomas. Staining was seen only in lesions located within 4 cm of the probe. Thus B-Flow ultrasonography using Levovist was proved useful for evaluating vascularity of superficially located.
