| Summary: | Abstract Background The American College of Radiology has proposed a risk stratification system for assessment of indefinite adnexal masses on ultrasound, called “Ovarian-Adnexal Reporting and Data System for Magnetic Resonance Imaging” (O-RADS MRI). This system classifies the adnexal masses into six categories according to their risk of malignancy based on the assessment of the solid and fluid portions of an adnexal mass on dynamic contrast-enhanced (DCE) MRI However, in some clinical scenarios the acquisition of DCE-MRI may be a provocation due to its long acquisition time and image post-processing. The purpose of this study was to evaluate the performance of the O-RADS MRI score using enhanced non- DCE-MRI in assessment of adnexal masses. Results When considering ORADS 3 as benign, ORADS MRI yielding 93.3% sensitivity, 92.3% specificity, 93.3% PPV, 92.3% NPV and 96.4% total accuracy. When considering ORADS 3 as malignant, ORADS MRI yielding 100% sensitivity, 80.8% specificity, 85.7% PPV, 100% NPV and 91.1% total accuracy. Conclusion ORADS MRI score on basis of enhanced non-DCE-MRI had high sensitivity, specificity and accuracy in differentiating benign from malignant adnexal masses. |
