Contrast-Enhanced Ultrasonography for Assessment of Tumor Vascularity in Hepatocellular Carcinoma

摘要

ObjectiveStudies have shown that angiogenesis is a critical factor for tumor growth and metastasis in a variety of human tumors. Although various methods have been tried to assess vessels in tumors, including microvessel density (MVD), assessment of tumor vessels by radiologic techniques is not well established. The aim of this study was to investigate the efficacy of contrast-enhanced ultrasonography (CEUS) in determining the tumor vascularity of hepatocellular carcinoma (HCC).
