PURPOSE
To identify the effects of shear wave elastography in the fetus for evaluation in widespread use.
MATERIALS AND METHODS
The Health Risk Assessment method proposed by the National Research Council was used with literature to evaluate the safety of shear wave elastography for the fetus regarding its potential effects in human tissues.
RESULTS
The experimental and epidemiologic data from 25 articles showed that shear wave elastography maintained the same thermal effect as pulsed Doppler ultrasound already authorized in obstetrics, and that cavitation effect on fetal tissue is improbable. Nonetheless, the vibratory character of shear waves could induce displacement of fetal tissue while potential effects of very short duration energy peaks of the radiation force focused wave front remain unknown.
CONCLUSION
The actual knowledge does not provide enough information to assess the effects of shear wave elastography on fetal tissues, thus these points have to be explored by further experimental studies.
目的
确定剪切波弹性成像在胎儿评估中的广泛应用效果。
材料与方法
采用美国国家研究理事会提出的健康风险评估方法，结合文献评估剪切波弹性成像对胎儿潜在组织影响的安全性。
结果
25 篇文章的实验和流行病学数据表明，剪切波弹性成像保持与已在妇产科授权的脉冲多普勒超声相同的热效应，而且对胎儿组织产生空化效应的可能性较小。然而，剪切波的振动特性可能会引起胎儿组织的位移，而辐射力聚焦波阵面的极短持续时间能量峰的潜在影响尚不清楚。
结论
现有知识没有提供足够的信息来评估剪切波弹性成像对胎儿组织的影响，因此这些问题需要通过进一步的实验研究来探讨。
