In the early stages of retrobulbar neuritis (RN), the optic disc appears normal on ophthalmoscopy. Therefore, the diagnosis of RN is usually made clinically. However, imaging tools are needed for precise diagnosis of RN, and usually MRI is used. In this study, we investigated the diagnostic performance of strain elastography (SE) and shear wave elastography (SWE) in patients with RN. Elastography is a new sonographic technique and a noninvasive ultrasound method for evaluating the elastic properties of tissues based on static compression: the elastographic techniques of SE compress the tissues axially, and SWE uses waves that are generated by transducers and interact with the tissue.

应变和剪切波弹性成像在球后神经炎的诊断中。

在球后神经炎（RN）的早期阶段，眼底镜检查发现视盘正常。因此，RN的诊断通常在临床上进行。但是，需要使用成像工具来精确诊断RN，并且通常使用MRI。在这项研究中，我们调查了应变弹性成像（SE）和剪切波弹性成像（SWE）在RN患者中的诊断性能。弹性成像是一种新的超声技术，是一种基于静态压缩来评估组织弹性特性的非侵入性超声方法：SE的弹性成像技术可轴向压缩组织，而SWE使用由换能器产生并与组织相互作用的波。
