Objective To investigate the endometrial thickness and echo patterns of healthy women, so as to provide a basis for the formulation of a standard to define normal endometrium in Chinese women. Method A total of 1872 married healthy women in Yongchuan District received transvaginal ultrasound examination. The endometrial sonograph was observed and endometrial thickness was measured for statistical analyses. Results In pre-menopausal women of different age groups, the endometrial thickness was increased and the endometrial echo was enhanced from the proliferative phase, ovulatory phase and secretory phase. The endometrial thickness varied significantly among different menstrual cycles, while no significant difference was observed in the endometrial thickness of a same menstrual cycle among women of different age groups. Pre-menopausal women had significantly different endometrial thickness when compared with post-menopausal women. Conclusion Through a general survey of women by transvaginal ultrasound, a large sample database can be established, which may contribute to the formulation of a standard to define normal endometrium in Chinese women and to help identify abnormal endometrium.
Objective To investigate the imaging characteristics of endometrial polyps by using transvaginal ultrasound and analyze the causes of misdiagnosis. Methods Fifty-seven patients pathologically diagnosed of endometrial polyps were retrospectively analyzed. Results The endometrial polyps had its own characteristics of ultrasound images, especially the lesion, size, shape, echo, border, color Doppler flow imaging (CDFI) and so on. Conclusion Endometrial polyps has some special features on ultrasound image. Inspection in the secretary period, along with endometrial hyperplasia of the merger as well as multiple myoma the merger may result in misdiagnosis.
