Abstract:
It is well known that contrast-enhanced sonography is valuable for the evaluation of tumoral vascularity in hepatocellular carcinoma (HCC). The knowledge of tumoral vascularity is important to diagnose HCC, to decide treatment method, and to assess therapeutic response after various treatments. Until now, various techniques of contrast-enhanced sonography have been investigated with HCCs. The purpose of this review is to describe various contrast-enhanced sonographic techniques for HCC in sequence of their development and to outline the advantages and limitation of each technique.
