Li YA, et al. - The researchers carried out this study to identify the MRI features of borderline epithelial ovarian tumors (BEOTs) and to differentiate BEOTs from malignant epithelial ovarian tumors (MEOTs). On MRI, BEOTs compared to MEOTs frequently indicated the following features: round or oval, with well-defined margins and clear cystic-solid interfaces, purely cystic or predominantly cystic with papillae or nodules, branching or exophytic papillae, with the presence of an ipsilateral ovary. The distinct morphological features of BEOTs and MEOTs could be identified on MRI, facilitating their discrimination.
