实时剪切波弹性成像技术对正常卵巢组织的定量研究#br#

目的 探讨卵巢弹性的影响因素，获取正常卵巢杨氏模量的参考值范围，评估及预测实时剪切波弹性成像（shear wave elastography， SWE）技术在卵巢储备功能方面的可行性。 方法 应用SWE超声诊断仪对常规经阴道超声检查的671例体检者的卵巢组织进行弹性测定，获得正常卵巢组织的杨氏模量值。 结果 围绝经期和绝经期卵巢杨氏模量值大于育龄期（P＜0.01）。育龄期中月经增生期与分泌期卵巢杨氏模量值差异无统计学意义（P＞0.05）。育龄期中不同年龄阶段组间卵巢杨氏模量值差异无统计学意义（P＞0.05）。育龄期卵巢杨氏模量最小值为（12.8±4.08） kPa、最大值为（16.9±4.86）kPa、平均值为（14.63±4.31） kPa。 结论 生理阶段影响正常卵巢组织的杨氏模量，月经周期对卵巢杨氏模量无影响，正常卵巢组织的硬度随着年龄的增长逐渐变硬。

Quantitative study of normal ovarian tissue by real-time shear wave elastography

Objective〖HTSS〗To investigate the factors influencing ovarian elasticity, obtain the reference range of young′s modulus of normal ovary, and evaluate and predict the feasibility of real-ltime shear wave elastography(SWE) in the ovarian reserve function. 〖WTHZ〗Methods〖HTSS〗The elasticity of the ovarian tissue of 671 subjects examined by conventional transvaginal ultrasonography was measured with SWE ultrasonography, and the young′s modulus value of normal ovarian tissue was obtained. 〖WTHZ〗Results〖HTSS〗The value of young′s modulus of ovary in perimenopausal and menopausal period was greater than that in reproductive period(P＜0.01). There was no significant difference in the young′s modulus between the reproductive age group and the secretion gyoup(P＞0.05). There was no statistically significant difference in the young′s modulus between different age gyoups during childbearing period(P＞0.05).The minimum、maximum and average young′s modulus of the ovary at the childbearing stage were (12.8±4.08) kPa， (16.9±4.86) kPa and (14.63±4.31) kPa. 〖WTHZ〗Conclusion〖HTSS〗The physiological stage affects the young′s modulus of the normal ovarian tissue, while the menstrual cycle has no effect on the young′s modulus of the ovary, The hardness of the normal ovarian tissue gradually hardens with the youth of age.
