To assess the role of shear wave elastography (SWE) in characterizing different endometrial and subendometrial pathologies.
Seventy-three women with pathologically proven endometrial and subendometrial pathologies were enrolled in this prospective study and assessed with transvaginal SWE. The elasticity values (in kiloPascals), and the ratio of mean elasticity of the endometrial lesion to myometrial elasticity (E/M ratio) were compared in different pathologies.
There was a statistically significant difference (P <.001) in the mean, minimum, and maximum elasticity of the pathologies as well as the E/M ratio (P <.00001). In the analysis of the subgroups, the mean elasticity of endometrial polyp was statistically significantly lower than other subgroups (P <.01), while submucosal leiomyoma and focal adenomyoma had significantly higher values than other subgroups (P <.01). No statistically significant difference was noted in the mean elasticity of carcinoma and hyperplasia (P-.19).
SWE is a potential adjunct to ultrasound that provides an additional paradigm to characterize endometrial and subendometrial masses.
评估剪切波弹性成像（SWE）在描述不同子宫内膜和子宫内病变中的作用。
本前瞻性研究纳入了 73 名经病理证实的子宫内膜和子宫内病变患者，并进行了经阴道 SWE 评估。比较了不同病变中的弹性值（千帕斯卡）和子宫内膜病变的平均弹性与子宫肌层弹性的比值（E/M 比值）。
病变的平均、最小和最大弹性以及 E/M 比值存在统计学显著差异（P<.001）。在亚组分析中，子宫内膜息肉的平均弹性显著低于其他亚组（P<.01），而黏膜下肌瘤和局灶性腺肌瘤的弹性值显著高于其他亚组（P<.01）。在癌和增生的平均弹性方面，差异无统计学意义（P>.19）。
SWE 是超声的一种潜在辅助手段，为描述子宫内膜和子宫内肿块提供了另一种模式。
