Ovarian volume ratio is a reliable predictor of ovarian torsion in girls without an adnexal mass

This retrospective study establishes ovarian volume ratio (OVR) as a highly accurate ultrasound predictor of ovarian torsion in premenarchal girls without adnexal masses. An OVR cutoff >2.5 demonstrated 100% sensitivity and 94% specificity, outperforming traditional metrics and remaining age-independent unlike ovarian width measurements.
