Background

The aim of this study was to use ultrasound vibro-elastography (UVE) for measuring surface wave speed and assessing mechanical properties of ex vivo porcine reproductive tissues, including the uterus, bladder, cornua and cervix.

Methods

In UVE, a 0.1-s harmonic vibration at low frequency was generated on the tissue surface with a handheld shaker. A linear-array ultrasound probe was used to measure the resulting surface wave propagation. Surface wave speeds of tissues were measured in the frequency range of 100–300 Hz. Mechanical properties of the tissue were calculated based on wave speed dispersion with frequency.

Findings

The obtained results showed that the surface wave speeds of porcine bladder, cervix, cornua and uterus increased with frequency. There were no statistically significant differences in the wave speeds or mechanical properties among the porcine bladder, cervix, cornua and uterus.

Interpretation

Experimental data obtained in this study may be used as a reference to study in vivo surface wave speed or mechanical properties for porcine or human reproductive tissues.

超声振动弹力图评估离体模型中猪生殖组织的机械性能。

背景

这项研究的目的是使用超声振动弹力描记术（UVE）来测量表面波速度并评估离体猪生殖组织（包括子宫，膀胱，角膜和子宫颈）的机械性能。

方法

在UVE中，使用手持式振荡器在组织表面产生了低频的0.1s谐波振动。线性阵列超声探头用于测量所得的表面波传播。在100–300 Hz的频率范围内测量组织的表面波速。根据波速随频率的色散计算组织的机械性能。

发现

所得结果表明，猪膀胱，子宫颈，角膜和子宫的表面波速随频率增加。猪膀胱，子宫颈，角膜和子宫之间的波速或机械性能无统计学差异。

解释

本研究中获得的实验数据可作为研究猪或人生殖组织的体内表面波速或机械性能的参考。
