Magnetic Resonance Imaging became a significant method in the examination of women with adnexal masses. There is multiparametric assessment, using conventional sequences, post contrast assessment as well as the Diffusion MRI weighted imaging. Evaluate the relevance of multiparametric MRI modalities in the identification of ovarian masses. A prospective study was conducted at Radiodiagnosis Department; Al-Zahraa University Hospital involved twenty patients with initial undetermined ovarian lesion. All patients were subjected to the full history taking and physical examination, laboratory investigation, ultrasound examination using trans-abdominal, trans-vaginal ultrasound and MR imaging. This study was conducted on 20 female patients ranged from 21 to 53 years old, about 60 % of lesions were mixed solid and cystic in composition, with more than half of them showed bright T2 signal, DWI of for the 20 lesions were tested and showed that ADC value ≤ 0.96 × 10-3 mm2/s is the optimal cut off for differentiating between benign and malignant masses with sensitivity of 100%, specificity of 78.6%. Multiparametric MRI assessment aid and enhance the confidence in assessing or ruling out probable malignancy of adnexal masses.
