The study evaluated myometrial stiffness of normal uterus using 3T magnetic resonance elastography (MRE) in 48 women with a mean age of 37.54 ± 10.47 years. The average value of myometrial stiffness (UMS) was 2714 ± 300 Pa. A strong positive correlation was found between age and UMS (r = 0.814, p < 0.001). UMS was higher in postmenopausal women compared to women of reproductive age (p < 0.001). No significant associations were found with BMI, uterine size, pregnancy, parity, or oral contraceptive use. The study confirms the feasibility of the 3T MRE method and provides estimates for normal uteri, but larger prospective studies are needed for normative ranges.
