| 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, p<0.001 for Reviewer 1; r=0.567,
p<0.001 for Reviewer 2). The size of the cavernous hemangiomas did not show significant
correlation with the CT hemodynamics scores (p>0.05).
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. |
