This study aimed to demonstrate the cyclic changes of the boundary sharpness of uterine three zonal structures of young and middle-aged women on 3T using a 3D T2-weighted SPACE sequence during the menstrual cycle. Peri-ovulatory phase exhibited the clearest boundary sharpness of corpus zonal structures following by FP, LP and MP, while that of the cervix were almost well-defined during the menstrual cycle.
