Abstract

ABSTRAC. Background and objective: To discuss the value of ultrasound (US) and magnetic resonance imaging (MRI) in the evaluation of female patients with ovarian tumors.    Methods: This study was performed on 250 patients at University hospital and the National Cancer Institute who were referred to radiodiagnosis department from the Obstetric and Gynecology department during the period from March 2017 to March 2018. All patients were subjected to pathology assessment, transvaginal ultrasonography (TVUS) and MRI with diffusion-weighted imaging (MRI-DWI).   Results: The study group of 250 patients had a mean age of 38.85 ± 17.1 years. Lesions were classified according to histo-pathological analysis into benign (120 lesions, 48%) and malignant (130 lesions, 52%). Using US with Doppler, 105 cases were judged benign, and 145 cases were judged malignant. The sensitivity of the US with doppler examination the sensitivity was 81.51%, with 93.9% specificity, The positive predictive value (PPV) was 91%, and the NPV was 86%. MRI analysis indicated that the mean dimension of benign tumors was 7.6 ± 1.3 cm, while the mean dimension of malignant tumors was 12.3 ± 2.4 cm (p < 0.001). The sensitivity of MRI was 96.43%, specificity was 95.83%, PPV. The apparent diffusion coefficient (ADC) values were 1.85 ± 0.58 for benign tumors and 0.84 ± 0.16 for malignant tumors. MRI-DWI showed 100% sensitivity, 93% specificity, 95.5% PPV, and 98% NPV.   Conclusion: MRI-DWI are promising techniques for the evaluation and characterization of ovarian cancer.
