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.
