Synopsis

Keywords: Pelvis, Normal developmentThis study aimed to investigate the correlation between hiatus area and age in healthy women. 552 female subjects, divided into four groups (young, young-middle, middle, middle-elderly) based on age, were selected to underwent pelvic T2-weighted MRI for measuring hiatus area. Age showed a positive correlation with hiatus area. Also, statistically significant difference in hiatus areas was found between any two groups, except for between young-middle and middle group, and between middle and middle-elderly group. We thus proved that hiatus area of healthy women increases with age, which might serve as a reference standard in clinic.
