In this prospective study, seventy-six patients (PCOS group; n = 36, multifollicular ovary group; n = 40) were evaluated by 2-D and 3-D ultrasonography. VOCAL programme, echogenicity, number of follicles and blood flow parameters were evaluated. The patients with PCOS had a higher total ovarian volume, mean stromal volume and stromal echogenicity (18.6 ± 4.75 to 10.2 ± 3.4 < .01; 12.23 ± 2.53 to 5.02 ± 2.44 = .02; score 1:28 to 10 < .01, respectively). There was no statistically significant difference in terms of mean RI and PI values between the groups ( > .05). 3 D power Doppler parameters included VI, FI, and VFI values of the patients with PCOS were higher when compared to those of the patients with multifollicular ovary (3.82 ± 2.65 to 1.78 ± 1.2, < .01; 50.76 ± 4.45 to 40.6 ± 3.64, = .03; and 2.34 ± 1.02 to 1.12 ± 0.65, = .02, respectively). Our results revealed that total ovarian volume, stromal volume and echogenicity; VFI, VI, and FI could be useful for differential diagnosis in women with PCOS and multifollicular ovaries.Impact statement Ultrasonography is considered the new diagnostic tool for PCOS. Enlarged ovaries with multiple small follicles peripherally located around increased ovarian stroma with increased stromal echogenicity are the sonographic features of polycystic ovaries. 3-D Doppler ultrasonography may be more specific in the determination of multifollicular and polycystic ovaries when compared to RI and PI in 2-D Doppler ultrasonography. Moreover, 3-D power Doppler ultrasonography could be useful for differential diagnosis in women with PCOS and multifollicular ovaries. In clinical practice, the differentiation of multifollicular ovaries and polycystic ovaries (PCO) is difficult with the use of 2-D sonography alone. Therefore, 3-D ultrasound and power Doppler may also be used in addition to 2-D ultrasound for the differentiation of multifollicular ovaries and PCO.
在这项前瞻性研究中，通过 2D 和 3D 超声检查评估了 76 名患者（多囊卵巢综合征组；n=36，多卵泡卵巢组；n=40）。评估了 VOCAL 方案、回声、卵泡数量和血流参数。多囊卵巢综合征患者的总卵巢体积、平均间质体积和间质回声较高（18.6±4.75 至 10.2±3.4 < .01；12.23±2.53 至 5.02±2.44 = .02；评分 1：28 至 10 < .01）。两组间平均 RI 和 PI 值无统计学差异（ > .05）。与多卵泡卵巢患者相比，多囊卵巢综合征患者的 3D 能量多普勒参数包括 VI、FI 和 VFI 值较高（3.82±2.65 至 1.78±1.2， < .01；50.76±4.45 至 40.6±3.64， = .03；和 2.34±1.02 至 1.12±0.65， = .02）。我们的结果表明，总卵巢体积、间质体积和回声；VFI、VI 和 FI 可用于多囊卵巢综合征和多卵泡卵巢妇女的鉴别诊断。
超声检查被认为是多囊卵巢综合征的新诊断工具。多囊卵巢的超声特征是外周多个小卵泡环绕增大的卵巢间质，间质回声增强。与 2D 多普勒超声相比，3D 多普勒超声在确定多卵泡和多囊卵巢方面可能更具特异性。此外，3D 能量多普勒超声可用于多囊卵巢综合征和多卵泡卵巢妇女的鉴别诊断。在临床实践中，仅使用 2D 超声很难区分多卵泡卵巢和多囊卵巢（PCO）。因此，除了 2D 超声外，3D 超声和能量多普勒也可用于多卵泡卵巢和 PCO 的鉴别诊断。
