PURPOSE: The purpose of this study is to investigate the correlation between
hemodynamics on three-phase CT and
ultrasonography echogenecity of small hepatic
cavernous hemangiomas (0.5 - 3 cm). MATERIALS AND
METHODS: A total of 158 hepatic
cavernous hemangiomas in 139
patients with normal
liver parenchyma,
who underwent
ultrasonography and dynamic CT, were analyzed retrospectively over a six-year period. Two
radiologists performed independent
analysis of the echogenecity (hyperechoic to hypoechoic) on
ultrasonography and
hemodynamics (slow to rapid) on CT images using five-grade
scales . Correlation between
ultrasonography echogenecity scores and CT
hemodynamics scores was examined using Spearman's correlation
analysis . CT
hemodynamics scores were also evaluated with
respect to the size of the hepatic
cavernous hemangiomas using Spearman's correlation
analysis .
RESULTS: The
ultrasonography echogenecity scores showed significant correlation with the CT
hemodynamics scores (r=0.364, p0.05).
CONCLUSIONS: More rapid filling of
contrast materials in small hepatic
cavernous hemangiomas on dynamic CT suggests a greater decrease in echogenecity on
ultrasonography and the echogenicity of small hepatic
cavernous hemangiomas on
ultrasonography can be predicted based on their
hemodynamics on dynamic CT.
