Differentiation of hepatic sclerosed hemangiomas from cavernous hemangiomas based on gadoxetic acid–enhanced magnetic resonance imaging features
Journal of Computer Assisted Tomography Sep 23, 2019
Hwang J, et al. - Nine individuals with hepatic sclerosed hemangiomas and 36 patients with cavernous hemangiomas (control group) who underwent gadoxetic acid-enhanced MRI were incorporated in this study to assess the imaging characteristics of a hepatic sclerosed hemangioma by contrasting them with those of cavernous hemangioma. In comparison with controls, individuals with sclerosed hemangiomas revealed significantly more irregular tumor margin on hepatobiliary phase images, peritumoral arterial enhancement, and a lower proportion of hyperintensity on heavily T2-weighted images. Moreover, the sclerosed hemangioma group had significantly more common atypical enhancement patterns compared with the control group. Nonetheless, the mean apparent diffusion coefficient value of hemangiomas was not significantly distinctive among the two groups. Thus, gadoxetic acid-enhanced MRI can assist in distinguishing amongst hepatic sclerosed hemangiomas and cavernous hemangiomas.
