Magnetic resonance imaging of uterine version in a multiethnic, nulliparous, healthy female population.
To determine measurement and topography of uterine position in asymptomatic women with different ethnicity. 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. 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). The degree of uterine version is different in healthy, nulliparous European/Caucasian and non-Caucasian women.
