Abstract

Background: This study aims to determine the normal values of orbital structures according to sex in healthy adults.

Methods: Diameters of extraocular muscles, the width of the optic nerve sheath diameter, the length of the inter-zygomatic line, ocular bulb length, and globe position were measured in the T1-weighed MR (magnetic resonance) images in 204 orbits of 102 individuals.

Results: The mean values of the diameters of the extraocular muscles in males and females were as follows: medial rectus, 3.96 ± 0.52 and 3.58 ± 0.53 mm; lateral rectus, 3.47 ± 0.61 and 3.15 ± 0.48 mm; inferior rectus, 4.47 ± 0.53 and 4.07 ± 0.48 mm; superior rectus, 4.44 ± 0.64 and 4.01 ± 0.56 mm; and superior oblique, 3.68 ± 0.49 and 3.45 ± 0.44 mm. The length of the interzygomatic line in males and females were 102.68 ± 3.89 and 96.95 ± 3.4 mm, the ocular bulb length was 23.33 ± 1.32 and 22.83 ± 1.1 mm, the globe position was 7.66 ± 1.33 and 7.3 ± 1.39 mm, and the width of the optic nerve sheath diameter was 4.65 ± 0.62 and 4.28 ± 0.51 mm, respectively. All measurements were significantly greater for males than for females (p < 0.05).

Conclusions: We believe that a practical and quantitative method will be provided by this study for the diagnosis and determination of the normative values of orbital structures.

使用磁共振成像方法评估健康成年人眼眶结构的正常测量值。

背景：本研究旨在确定健康成年人眼眶结构的正常值：本研究旨在确定健康成年人眼眶结构的正常值（根据性别）：方法：在 102 人的 204 个眼眶的 T1 称重 MR（磁共振）图像中测量眼外肌直径、视神经鞘直径宽度、颧间线长度、眼球长度和眼球位置：男性和女性眼外肌直径的平均值如下：内侧直肌，3.96 ± 0.52 mm 和 3.58 ± 0.53 mm；外侧直肌，3.47 ± 0.61 mm 和 3.15 ± 0.53 mm。61 和 3.15 ± 0.48 毫米；下直肌，4.47 ± 0.53 和 4.07 ± 0.48 毫米；上直肌，4.44 ± 0.64 和 4.01 ± 0.56 毫米；上斜肌，3.68 ± 0.49 和 3.45 ± 0.44 毫米。男性和女性的颧间线长度分别为 102.68 ± 3.89 和 96.95 ± 3.4 毫米，眼球长度分别为 23.33 ± 1.32 和 22.83 ± 1.1 毫米，眼球位置分别为 7.66 ± 1.33 和 7.3 ± 1.39 毫米，视神经鞘直径宽度分别为 4.65 ± 0.62 和 4.28 ± 0.51 毫米。所有测量值男性均明显大于女性（P < 0.05）：我们相信，这项研究将为诊断和确定眼眶结构的正常值提供一种实用的定量方法。

期刊介绍： TomographyTM publishes basic (technical and pre-clinical) and clinical scientific articles which involve the advancement of imaging technologies. Tomography encompasses studies that use single or multiple imaging modalities including for example CT, US, PET, SPECT, MR and hyperpolarization technologies, as well as optical modalities (i.e. bioluminescence, photoacoustic, endomicroscopy, fiber optic imaging and optical computed tomography) in basic sciences, engineering, preclinical and clinical medicine. Tomography also welcomes studies involving exploration and refinement of contrast mechanisms and image-derived metrics within and across modalities toward the development of novel imaging probes for image-based feedback and intervention. The use of imaging in biology and medicine provides unparalleled opportunities to noninvasively interrogate tissues to obtain real-time dynamic and quantitative information required for diagnosis and response to interventions and to follow evolving pathological conditions. As multi-modal studies and the complexities of imaging technologies themselves are ever increasing to provide advanced information to scientists and clinicians. Tomography provides a unique publication venue allowing investigators the opportunity to more precisely communicate integrated findings related to the diverse and heterogeneous features associated with underlying anatomical, physiological, functional, metabolic and molecular genetic activities of normal and diseased tissue. Thus Tomography publishes peer-reviewed articles which involve the broad use of imaging of any tissue and disease type including both preclinical and clinical investigations. In addition, hardware/software along with chemical and molecular probe advances are welcome as they are deemed to significantly contribute towards the long-term goal of improving the overall impact of imaging on scientific and clinical discovery.
