Background: Ovarian tumors are one of the prevalent gynecological tumors. They are the fifth commonest tumor in women. The therapeutic strategy depends on whether the tumor is benign, borderline or malignant. They always cause nonspecific symptoms at early stages and diagnosed at advanced stages. We tried to test and compare the sensitivity and accuracy of diffusion-weighted imaging (DWI) and MR perfusion in the diagnosis of ovarian tumors among fifty patients with ovarian masses who collected after meeting the inclusion criteria depending on grayscale sonographic findings after the approval of the ethical committee of our institution. The sensitivity and accuracy of the techniques were compared. Results: The surgical and pathological reports of our patients proved a non-tumorous lesion in three patients. They also proved benign ovarian tumors in 18/47 (38.3%) patients, borderline tumors in 4/47 (8.5%) patients and malignant ovarian tumors in 25/47 (53.2%) patients. According to conventional MRI, ovarian tumors could be diagnosed with sensitivity 92%, specificity 61.11%, PPV 76.7%, NPV 84.6% and accuracy 79.1%. DWI and MR perfusion showed the same results where they showed sensitivity 98%, specificity 83%, PPV 90%, NPV 98% and accuracy 93% with ADC cutoff value 1 × 10− 3 mm 2 /s. Conclusion: Diffusion-weighted imaging and MR perfusion are useful in the diagnosis of ovarian tumors with approximately the same sensitivity and positive impact on operative management.
