I-47: Doppler Ultrasound Diagnosis of Intrauterine Lesions

Background In patients with abnormal uterine bleeding, transvaginal ultrasound (TVS) is the first-line diagnostic approach to exclude endometrial pathology. If a thickened endometrium suggests endometrial pathology, sonohysterography, office hysteroscopy or dilatation and curettage are the second-line tests preferred, depending on availability and on the suspected pathology, to exclude malignancy and to aid in the decision on management of any pathology found. However, these invasive tests cause patient discomfort and increase the cost of the examination in comparison with TVS. Discriminating between endometrial polyps and submucous myomas can cause difficulties using traditional greyscale ultrasound, even with instillation of saline. The malignancy potential of endometrial polyps is still dubious. Power Doppler is a new technology with various advantages over conventional Color Doppler. It is based on the amplitude of the Doppler signal but not on the Doppler frequency shift. It is insonation angle independent, with no aliasing, and is more sensitive to low-velocity blood flow. Power Doppler is useful to discriminate between submucous myomas and endometrial polyps. The use of power Doppler in the evaluation of intracavitary lesions may prove to play a role in avoiding unnecessary surgery. To compare power Doppler flow mapping characteristics of endometrial polyps and submucosal fibroids and analyze whether two different power Doppler characteristics, singlevessel pattern and rim-like vessel pattern, can help to differentiate these focal endometrial lesions. In this presentation,I will discuses about differentiation intrauterine lesions in Color Doppler. MaterialsAndMethods N;Results N;Conclusion N;
