多囊卵巢综合征超声诊断进展

Ultrasound diagnosis of polycystic ovary syndrome

超声技术作为一项重要的非侵人性检查方法,在多囊卵巢综合征(PCOS)诊断中的作用越来越重要,2003年公布的PCOS鹿特丹诊断标准,第一次包含了多囊卵巢的形态学描述,为PCOS诊断的标准化迈出了重要的一步。然而,自鹿特丹标准公布以来,有关超声检查的客观性、检查者间一致性及可重复性欠佳等问题使鹿特丹标准备受争议。此外,随着超声技术的发展,仪器分辨率的不断提高,建立在二维超声基础上的鹿特丹超声诊断标准的适用性也受到越来越多质疑。三维超声及三维能量多普勒超声技术可能成为一项重要的新技术用于PCOS诊断。本文就超声技术在PCOS中的诊断作用及进展做一综述,旨在有助于更深刻理解PCOS的发病机理。

A non-invasive ultrasound （US） diagnostic tool plays an increasingly important role in the examination of polycystic ovary syndrome （PCOS）. The morphologic description of polycystic ovary was firstly included in ultrasonic diagnostic criteria of Rotterdam Consensus in 2003, which made a momentous step for standardizing diagnostic criteria of PCOS. However, several issues, such as objectivity, consistency among various examiners and dissatisfied reproducibility,are still controversial since Rotterdam Consensus was released. Furthermore, with the advances in ultrasonographic technology and the improvement of high-resolution devices, there are more and more doubts about feasibility of Rotterdam Consensus which based on two-dimensional ultrasonic technique. Three-dimensional ultrasound （3D-US） and three-dimensional color power angiography （3D-CPA） techniques may provide a new way for the diagnosis of PCOS. In this article, the role of ultrasound techniques in the diagnosis of PCOS and up-to-date progress are reviewed,in order to get a deeper understanding of the underlying pathogenic mechanism of PCOS.
