ABSTRACT
Objective To explore the relationships between the quantitative parameters for contrastenhanced ultrasonography(CEUS) in hepatocellular carcinoma (HCC) and arteries in neoangiogenesis.Methods One hundred and fifteen HCCs in CEUS were analyzed off-line with dynamic vascular curve of ImageArena and immunohistochemical stained in the tissue slices.Parameters including maximum of intensity(IMAX),rise time(RT),time to peak(TTP),mean trasit time corresponding to the center of gravity(mTT) ,rise slope(RS) and washout time(WT) were analyzed by statistics.Unpaired arteries(UAs)of 82 HCC cases were succesfully stained.Results The number of UAs had moderate correlation with RT (r = - 0.446),TTP (r = - 0.432) and RS (r = 0.431) (P < 0.05),and it had mild correlation with IMAX (r = 0.303) ,WT (r = 0.285) (P <0.05).Conclusions Neoangiogenesis is a functional adaptation to altered vascular dynamics.Quantitative parameters of CEUS,reflecting hemodynamics of tumors,are correlated with UAs.
