Ultrasound O-RADS achieved an overall accuracy of 84.6% in differentiating ovarian lesions.
With a sensitivity of 83.7% and specificity of 85.0%, ultrasound O-RADS performs reliably against MRI.
Performance improved notably in postmenopausal women and for larger lesions over 5 cm.
Utilizing ultrasound O-RADS can potentially decrease unnecessary MRI referrals in resource-limited settings.
