Differentiation between benign and malignant ovarian masses using multiparametric MRI
To investigate the capabilities of multiparametric MRI including dynamic contrast enhanced (DCE) perfusion and diffusion-weighted imaging (DWI) to discriminate between benign and malignant ovarian masses. A total of 43 women with a total of 43 ovarian masses were retrospectively included. They had a mean age of 51.26±18.05 (SD) years (range: 20-88years). Twenty women had benign and 23 had malignant ovarian tumors. All women had multiparametric MRI examinations including DWI (b50-b800) and DCE perfusion imaging at 1-5T. Results of DWI (apparent diffusion coefficient [ADC], b-800) and DCE imaging (volume transfer coefficient [K Mean ADC was significantly lowed in malignant tumors (0.92±0.25 [SD]×10 Multiparametric MRI has high accuracy in discrimination between benign and malignant ovarian masses. Therefore, adding these methods to the more common MRI protocol can help select the best treatment option in women with ovarian mass.
