Single-level dynamic spiral CT of hepatocellular carcinoma: correlation between imaging features and density of tumor microvessels.

Aim: To investigate the correlation of enhancement features of hepatocellular carcinoma (HCC) revealed by single-level dynamic spiral CT scanning (DSCT) with tumor microvessel density (MVD), and to determine the validity of DSCT in assessing in vivo tumor angiogenic activity of HCC.

Methods: Twenty six HCC patients were diagnosed histopathologically. DSCT was performed for all patients according to standard scanning protocol.
