Computed tomography currently has a prominent role in diagnosis and evaluation of vertebral column. On the other hand, a thorough knowledge about vertebral column property in normal state is prerequisite an accurate diagnosis of different abnormalities in this region.
The purpose of this study was to present a complete and exact descriptive and morphometric evaluation of thoracic vertebrae in rabbits with computed tomography. In images which were constructed by CT, several structures and different parts of the thoracic vertebrae have been named.
Ten healthy, mature, White New Zealand rabbits were evaluated. The morphologic and morphometric parameters of the thoracic vertebrae were studied. In this study, several parameters of thoracic vertebrae, such as vertebral body height, spinous process height, transverse process length, transverse process width, etc., were measured by computed tomography.
Some parameters, such as spinal canal height, spinal canal width, pedicle length, pedicle width, end plate width, and endplate height, had no significant difference through thoracic vertebrae but other parameters, such as vertebral body height, transverse process length, transverse process width, spinous process angle, transverse process angle, and vertebral body length, had a significant difference.
In this study, a comprehensive anatomic atlas of CT anatomy of the thoracic vertebrae was produced for use by veterinary radiologists, clinicians, and surgeons. Finally, we must mention these two important points: (1) Many of the differences observed between rabbits and humans are based on the way the trunks of these two creatures are located on the ground and the differences in the way their bodies move. (2) In studies that are done by modelling humans on animals, it should be noted that the terms used in animal anatomy are different and the names are used using the principles of veterinary anatomy.
计算机断层扫描（CT）目前在脊柱的诊断和评估中具有突出的作用。另一方面，准确诊断该区域的不同异常情况，需要对脊柱的正常状态有全面深入的了解。
本研究旨在通过 CT 对兔的胸椎进行全面准确的描述和形态计量评估。在 CT 构建的图像中，对胸椎的几个结构和不同部位进行了命名。
对 10 只健康、成熟的新西兰大白兔进行评估。研究了胸椎的形态和形态计量参数。在本研究中，通过 CT 测量了胸椎的几个参数，如椎体高度、棘突高度、横突长度、横突宽度等。
一些参数，如椎管高度、椎管宽度、椎弓根长度、椎弓根宽度、终板宽度和终板高度，在整个胸椎中没有显著差异，但其他参数，如椎体高度、横突长度、横突宽度、棘突角度、横突角度和椎体长度，有显著差异。
本研究为兽医放射科医生、临床医生和外科医生制作了一份全面的 CT 解剖胸椎图谱。最后，我们必须提到这两点：（1）兔和人之间观察到的许多差异是基于这两种动物的躯干在地面上的位置以及它们身体运动方式的差异。（2）在对动物进行人体建模的研究中，应注意到动物解剖学中使用的术语不同，并且使用兽医解剖学的原理来命名。
