Sonoelastography is a novel technique that uses ultrasound waves to assess the elasticity of tissues noninvasively. It provides an ultrasound-based method to detect and display the relative stiffness of tissue. The main principle of sonoelastography is the measurement of tissue distortion in response to external compression. Changes in elasticity and tissues deformation elicited by compression are measured, processed and then shown in real time presentation with color-coded elastograms. Most of the elastography applications are well known and have been described in detail in adults, e.g. evaluation of liver fibrosis or thyroid nodules. Similarly, most of sonoelastographic studies are based on groups of adults. The purpose of this review article is to bring this technology closer to pediatric clinicians and to summarize some of its current clinical applications that are being pursued. In this part we take into consideration utility of elastography in evaluation pathologies of musculoskeletal system, lymphatic nodes, thyroid, kidneys in pediatric patients and also elastography of placenta.
超声弹性成像术是一种利用超声波无创评估组织弹性的新技术。它提供了一种基于超声的方法来检测和显示组织的相对硬度。超声弹性成像术的主要原理是测量组织在外部压迫下的变形情况。测量、处理因压迫引起的弹性变化和组织变形，然后通过彩色编码弹性图实时呈现出来。大多数弹性成像应用是众所周知的，并且在成人中已有详细描述，例如肝纤维化或甲状腺结节的评估。同样，大多数超声弹性成像研究都是基于成年人群体。这篇综述文章的目的是让儿科临床医生更了解这项技术，并总结一些目前正在探索的临床应用。在这部分内容中，我们考虑了弹性成像术在评估儿科患者肌肉骨骼系统、淋巴结、甲状腺、肾脏病变以及胎盘弹性成像方面的效用。
