Summary: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.
