Abstract
Objectives: To evaluate the diagnostic performance of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) for the characterization of complex ovarian tumors, by using histologic findings as the reference standard.
Patients & methods: 25 patient (age range from 16 to 74 year) with twenty five complex ovarian masses underwent DCE-MRI before surgical excision. The study included 9 benign,16 malignant masses. The following kinetic parameters were analyzed: enhancement amplitude (EA) in the form of MRE%, time to peak in the form of T max & maximal slope (MS) & correlated with histopathological results.
Results: DCE-MRI achieved higher overall accuracy (78%) & specificity (88.8%) than conventional MRI. MRE% was higher for malignant than for benign (p= 0.004) & malignant masses (p= 0.036). T max was of shorter duration in malignant than in benign (p= 0.002). MS was the best criterion to differentiate between benign & malignant tumors. Type III curve was specific for invasive malignant tumors.
