Magnetic resonance imaging of uterine version in a multiethnic, nulliparous, healthy female population.

OBJECTIVE: To determine measurement and topography of uterine position in asymptomatic women with different ethnicity. STUDY DESIGN: The angle and direction of uterine version were measured using magnetic resonance imaging in nulliparous, young volunteers from 5 ethnic groups (Emiratis, other Arabs, Indians/Pakistanis, Filipinos and Europeans/Caucasians; N = 55) and compared using Europeans/Caucasians as the reference group. RESULTS: The uterus was anteverted on the vagina in 46 (83.6%) and retroverted in 9 (16.4%) women, with no significant difference between Europeans/Caucasians and non-Caucasians. The angle of uterine version was significantly less (i.e., the cervix was more anteverted or retroverted on the vagina) in Europeans/Caucasians as compared to other women (p = 0.002), particularly Indians/Pakistanis (p < 0.00001). CONCLUSION: The degree of uterine version is different in healthy, nulliparous European/Caucasian and non-Caucasian women.
