Magnetic resonance elastography (MRE) can provide insight into the biomechanical properties of tissues. Yet, there is a lack of widespread utilization of MRE for evaluation of the head and neck region, particularly the orbit. This article describes the preliminary MRE findings for imaging of the orbit in healthy human subjects and evaluates its feasibility and technical considerations. Two healthy volunteers were recruited for participation. A standard liver driver was positioned over the forehead of the volunteer, after which a 3T scanner was used to obtain MRE images of the orbit at 8 and 20 kPa. Resulting image quality and strain patterns were assessed. Basic viscoelastic information was visualized on orbit elastograms obtained at both 8 and 20 kPa, with both image sets displaying increased strain in the posterior globes. Image quality appeared better at 8 kPa than at 20 kPa. While the development of specialized devices and techniques requires further investigation to optimize image quality, MRE is feasible for effectively visualizing viscoelastic properties of intra- and periorbital tissues.
磁共振弹性成像（MRE）能够深入了解组织的生物力学特性。然而，MRE在头颈部区域，尤其是眼眶的评估中缺乏广泛应用。本文描述了健康人体受试者眼眶成像的初步MRE结果，并评估了其可行性和技术考量。招募了两名健康志愿者参与。在志愿者前额放置标准肝脏驱动装置，之后使用3T扫描仪在8kPa和20kPa下获取眼眶的MRE图像。对所得图像质量和应变模式进行评估。在8kPa和20kPa下获得的眼眶弹性图上均能可视化基本的粘弹性信息，两组图像均显示眼球后部应变增加。8kPa时的图像质量似乎优于20kPa时。虽然需要进一步研究开发专门的设备和技术以优化图像质量，但MRE对于有效可视化眶内和眶周组织的粘弹性特性是可行的。
