三维腔内超声在多囊卵巢综合征诊断中的应用

Application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome

探讨多囊卵巢综合征（PCOS）患者卵巢的三维超声容积参数特点.检测40例PCOS患者（PCOS组）和40例月经正常者（对照组）的卵巢三维容积指标,应用接受者操作特性曲线（ROC曲线）比较各项指标的诊断价值.PCOS组的卵巢容积、间质容积以及两者之比显著大于对照组（均P＜0.05）.ROC曲线分析表明卵巢容积、间质容积和两者之比用于诊断PCOS更有意义（曲线下面积分别为0.876、0.926、0.886）,其中间质容积在诊断PCOS中价值最高,其截断值为7.52 cm3时,敏感性为88%,特异性为90%.三维腔内超声容积测量能为PCOS的诊断提供更多定量依据.

To evaluate the application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome （ PCOS）. The three-dimensional volumes of ovary were measured by intracavitary ultrasonography in 40 PCOS patients and 40 normal controls. The diagnostic value of parameters derived from three-dimensional ultrasonography was evaluated by using the receiver operating characteristic （ROC） curve. The ovarian volume, stromal volume, and the stromal/total volume ratio in PCOS group were significantly higher than those in control group （both P 〈 0. 05 ） ; the area under ROC curve （ AUC ） of them were 0. 876, 0. 926, 0. 886 respectively. Among these parameters, stromal volume had the highest diagnostic value for PCOS, the cut-off value of which was 7.52 cm3 with a sensitivity of 88% and a specificity of 90%. Volume parameters of ovary measured by intracavitary three-dimensional ultrasonography can offer quantitative information for the diagnosis of PCOS.
