Abstract：
UNASSIGNED: This study aims to correlate pelvic ultrasound with female puberty and evaluate the usual ultrasound parameters as diagnostic tests for the onset of puberty and, in particular, a less studied parameter: the Doppler evaluation of the uterine arteries.
UNASSIGNED: Cross-sectional study with girls aged from one to less than eighteen years old, with normal pubertal development, who underwent pelvic ultrasound examination from November 2020 to December 2021. The presence of thelarche was the clinical criterion to distinguish pubescent from non-pubescent girls. The sonographic parameters were evaluated using the ROC curve and the cutoff point defined through the Youden index (J).
UNASSIGNED: 60 girls were included in the study. Uterine volume ≥ 2.45mL had a sensitivity of 93%, specificity of 90%, PPV of 90%, NPV of 93% and accuracy of 91% (AUC 0.972) for predicting the onset of puberty. Mean ovarian volume ≥ 1.48mL had a sensitivity of 96%, specificity of 90%, PPV of 90%, NPV of 97% and accuracy of 93% (AUC 0.966). Mean PI ≤ 2.75 had 100% sensitivity, 48% specificity, 62% PPV, 100% NPV and 72% accuracy (AUC 0.756) for predicting the onset of puberty.
UNASSIGNED: Pelvic ultrasound proved to be an excellent tool for female pubertal assessment and uterine and ovarian volume, the best ultrasound parameters for detecting the onset of puberty. The PI of the uterine arteries, in this study, although useful in the pubertal evaluation, showed lower accuracy in relation to the uterine and ovarian volume.

摘要：
■这项研究旨在将盆腔超声与女性青春期相关联，并评估通常的超声参数作为青春期发作的诊断测试，特别是,较少研究的参数：子宫动脉的多普勒评估。
■针对1岁至18岁以下女孩的横断面研究，正常的青春期发育，从2020年11月至2021年12月接受了盆腔超声检查。Tharche的存在是区分青春期和非青春期女孩的临床标准。使用ROC曲线和通过Youden指数（J）定义的截止点评估超声参数。
■60名女孩被纳入研究。子宫体积≥2.45mL的敏感性为93%，特异性为90%，PPV为90%，用于预测青春期发作的NPV为93％，准确性为91％（AUC0.972）。平均卵巢体积≥1.48mL的敏感性为96%，特异性为90%，PPV为90%，NPV为97%，准确率为93%（AUC0.966）。平均PI≤2.75具有100%的灵敏度，48%特异性，62%PPV,预测青春期开始的100%NPV和72%准确度(AUC0.756)。
■盆腔超声被证明是女性青春期评估以及子宫和卵巢体积的绝佳工具，检测青春期开始的最佳超声参数。子宫动脉的PI,在这项研究中，虽然在青春期评估中很有用，显示与子宫和卵巢体积有关的准确性较低。
