Aim/objective This study aims at emphasizing the role of Diffusion-weighted MR imaging in characterization of ovarian tumors at reproductive age group. Background Ovarian tumors are relatively common and represent approximately 6% of female malignancies. Although the final diagnosis of an ovarian tumor is based on the histological examination, the accurate characterization of ovarian masses as benign or malignant could avoid unnecessary surgery and allow young females (in reproductive age group) to go for conservative treatment. Diffusion Weighted Imaging (DWI) depends on Brownian motion phenomenon which describe the random motion of molecules of water and how it is affected by tissue cellularity and microstructures. As a result, malignant ovarian tumors due to its hyper cellular nature show diffusion restriction, unlike most benign tumors. Patients and Methods MRI Unit, Radio diagnosis department, Meet Ghamer oncology center and Banha University hospital. A cross sectional study, included 30 women who presented with suspicious adnexal masses on previous ultrasound examination and referred for further assessment by DW-MRI. Post-menopausal females and females with contraindications to MRI (e.g. cardiac prosthesis, metallic implants and sever claustrophobia) are excluded. Results The study included 30 women ranging in age between 19 and 49 years with mean age 33.03 ± 9.9. Out of 30 cases, 11 had malignant ovarian tumors while 19 had benign tumors. Conclusion Adding DWI to conventional MRI increases the specificity and accuracy of MRI study.
