Abstract

Introduction: Simple cystic ovarian tumors are benign, whereas ovarian tumors with solid components within the cyst may be either malignant or benign. Malignant ovarian tumor”s tissues are characterized by neoangiogenesis, which manifests on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) as early and intense contrast uptake. In contrast, benign ovarian tumor’s tissues are typically fibrous and hypovascular, demonstrating minimal contrast uptake with gradual enhancement in the delayed phase. These characteristics allow for the differentiation between malignant and benign ovarian tumors. Study Objective: To evaluate the diagnostic value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in differentiating malignant from benign solid components in ovarian tumors. Methods: A total of 127 cases of ovarian tumors with solid components were included, comprising 90 cases of malignant ovarian tumors and 37 cases of benign ovarian tumors. Methods: This was a descriptive, cross-sectional, prospective study. The diagnostic performance of DCE-MRI was compared with histopathological findings obtained postoperatively. Results: DCE-MRI demonstrated high diagnostic accuracy in distinguishing malignant from benign solid components in ovarian tumors.
