Abstract：
BACKGROUND:Knowledge of ovarian volume is important for diagnostic evaluations; however, normal ovarian volume studies on children and adolescents are lacking. OBJECTIVE:This study aimed to analyze age-specific ovarian volume and identify the diverse factors that contribute to ovarian diagnoses. MATERIALS AND METHODS:We retrospectively enrolled 180 patients (0-18 years of age) with normal ovaries who underwent magnetic resonance imaging (MRI) between 2010 and 2018. MRI sequences included coronal and axial T2-weighted turbo spin echo (TSE) images and coronal T1-weighted TSE images. Ovarian volume was calculated by the standard ellipsoid formula. Age-specific ovarian volume, height, weight, height-adjusted total ovarian volume and body mass index were obtained. Linear regression analysis was used to predict ovarian volume. RESULTS:Six age groups (infant; early and late child, and early, middle and late adolescent) were described. The early adolescent group (10-12 years) had the highest rate of increase. In the middle adolescent period (13-15 years), the curve of ovarian volume appeared flat. CONCLUSION:Our findings provide age-specific references for ovarian volume.
