The Role of Contrast-Enhanced Ultrasonography in the Diagnosis and Treatment of Hepatic Tumors (Summary)
As described in Chap. 4 and 16, contrast-enhanced ultrasonography (US) plays two major roles in the diagnosis and treatment of hepatic tumors: differential diagnosis, and application in the treatment of hepatic tumors. It must be remembered, however, that characterization of a hepatocellular carcinoma (HCC), a borderline lesion associated with hepatocellular carcinoma, and a nodular lesion associated with liver cirrhosis can only be made with the aid of other diagnostic imaging methods or histological examination. In this sense, the first major role of contrast-enhanced US can be to diagnose a benign tumor for outpatients, avoiding further invasive examinations, such as biopsy or angiography.
