Ultrasonic assessment of the postmenopausal uterus

Abstract

Objectives: To assess the role of different forms of ultrasound in the evaluation of peri- and postmenopausal uterus.

Methods: B-mode ultrasound, colour and pulsed Doppler sonography, three-dimensional ultrasound and three-dimensional power Doppler sonography are non-invasive tools used repeatedly for assessing morphology and vascularity of the uterus and uterine lesions in peri- and postmenopausal patients.

Results: The application of transvaginal colour Doppler to the peri- and postmenopausal patients for the screening for endometrial and myometrial malignancy may be a viable option if combined with ovarian screening in the same scan. In this way the capital costs would be shared and oncological preventive medicine for postmenopausal women could be initiated. Three-dimensional and power Doppler ultrasound offers improved visualisation of uterine lesions, displays an entire volume, offers accurate volume estimation and enables retrospective review of stored data. Interactive rotation of power Doppler rendered images provides improved visualisation of the uterine vasculature.

Conclusions: Further technological development of the ultrasound imaging techniques could result in reduction of both the potential risks and economic cost of the invasive diagnostic procedures in postmenopausal patients such as dilatation and curettage operations. Same techniques can be used for early detection of endometrial malignancy in asymptomatic postmenopausal women as well as for prediction of the depth of myometrial invasion.
