Abstract：Objective To investigate the changes of thickness of uterine myometrium of normal females in different age groups detected by 3.0T MRI imaging technique .Methods The data of MRI images of normal uterus of 76 females were retrospectively analyzed ,and the thickness of uterine myometrium in uterine internal muscularis ( junctional zone ) and external muscularis was measured ,moreover ,the data were analyzed in the four different age groups .Results The median of thickness of uterine myometrium in junctional zone in 21~30 years group,31~40 years group,41~50 years group, ≥51 years group was 0.4cm,0.8cm,0.63cm,0.1cm,respectively, which in external muscularis was 1.2cm,1.1cm,1.2cm,1.2cm, respectively .There is no significant difference in the thickness of uterine myometrium in junctional zone between 31~40 years group and 41~50 years group , the thickness of uterine myometrium in junctional zone is the thickest in 31~40 years group and in 41~50 years group , the next in order 21~30 years group ,however , the thickness of uterine myometrium in junctional zone is the thinest in ≥51 years group.Moreover,there is no significant difference in the thickness of uterine myometrium in uterine external muscularis among the four age groups .Conclusion The change of thickness of junctional zone in different ages has a very important significance in the study of uterine diseases .
