摘要
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.
