Abstract

In vivo visualization of the optic nerve (ON) by computed tomography (CT) has important clinical applications, both realized and potential. An accurate CT analysis of the ON is, however, hampered by a number of technical limitations. Sinuosity and gaze-shift-related motility of the ON tend to increase the difficulties of demonstrating in a consistently satisfactory fashion this anatomical structure. Nevertheless, if rigid imaging criteria are followed, adequate visualization of the ON may be attained in the majority of patients. Simultaneous visualization of the ON and the eyeball permits establishment of a neuroocular index for clinical use.

摘要

通过计算机断层扫描（CT）对视神经（ON）进行体内可视化具有重要的临床应用价值，既有已实现的应用，也有潜在的应用。然而，对视神经进行准确的CT分析受到一些技术限制的阻碍。视神经的弯曲度和与注视转移相关的活动往往会增加以始终令人满意的方式显示这一解剖结构的难度。尽管如此，如果遵循严格的成像标准，大多数患者仍可实现对视神经的充分可视化。对视神经和眼球的同时可视化允许建立一个用于临床的神经眼指数。
