abstract
- Measurement of endometrial thickness with ultrasonography is a modality commonly used today. Its clinical importance and applications extend throughout the phases of the reproductive lives of women. In premenopausal women, endometrial thickness is used to monitor infertility treatment, while in postmenopausal women with abnormal uterine bleeding it is useful as an initial investigation for endometrial hyperplasia or cancer. Moreover, endometrial thickness can vary with the menstrual cycle and with the use of hormone replacement therapy or selective estrogen receptor modulators. In this review, the use of ultrasound to measure both the premenopausal and postmenopausal endometrium is discussed.
