Radiographic studies of Persian cat's cervical vertebrae can provide us with valuable information used in identifying its anatomical features, investigating various species of Persian cats and evaluating their cervical pathologies.
The present study aimed to investigate the anatomical and radiological features of cervical vertebrae in Persian cats to create a comprehensive and accurate reference for the normal range of cervical bones and joints that can be used for clinical decision-making and interpretation of radiographic findings in these cats.
The present descriptive-cross-sectional study included 10 adult Persian cats, including 5 males and 5 females. All cats underwent radiography in the dorsoventral, ventrodorsal, left lateral and right lateral recumbency. Then, anatomical investigations were performed.
According to our findings, Persian cats were different from other cat species in some cervical vertebral characteristics, which can be suggested as comparative anatomy in these species. The most important differences were as follows: the C3 and C7 had the lowest and highest spinous process height (SPH), respectively. The atlas had the highest transverse process width (TPW), which was significantly different with other cervical vertebrae (p ≤ 0.05). Moreover, the cervical vertebrae were not significantly different in vertical diameter of cranial vertebral foramen (VDCrVF) and transverse diameter of cranial vertebral foramen (TDCrVF) (p ≤ 0.05). The caudal surface of the atlantic vertebral arch had two dorsal and ventral tubercles. Also, the ventral crest of the axis was quite indistinct in the cranial part while becoming prominent in the caudal part. The C3 spinous process was a wide, small tubercle, while the C7 spinous process was extended vertically. Finally, the C6 transverse processes had a large ventrocranial tubercle forming a sagittal plate with cranial and caudal parts separated by a notch.
The accurate and comprehensive standard ranges obtained from the present study can be used for the interpretation of imaging results, clinical decision-making, and finding the normal and abnormal sizes of the cervical vertebrae and their processes in Persian cats.
对波斯猫颈椎的影像学研究可为识别其解剖特征、研究不同品种的波斯猫以及评估其颈椎病变提供有价值的信息。
本研究旨在探讨波斯猫颈椎的解剖学和影像学特征，为颈椎骨骼和关节的正常范围建立一个全面、准确的参考，为临床决策和这些猫的影像学结果解读提供依据。
本研究采用描述性横断面研究，纳入 10 只成年波斯猫，包括 5 只雄性和 5 只雌性。所有猫均在仰卧位进行背腹位、腹背位、左外侧位和右外侧位的放射摄影，然后进行解剖学研究。
根据我们的发现，波斯猫在一些颈椎特征上与其他猫种不同，这可以作为这些物种的比较解剖学特征。最重要的差异如下：C3 和 C7 的棘突高度（SPH）最低和最高。寰椎的横突宽度（TPW）最高，与其他颈椎明显不同（p ≤ 0.05）。此外，颈椎在颅椎孔的垂直直径（VDCrVF）和横径（TDCrVF）方面没有显著差异（p ≤ 0.05）。寰椎后弓的背侧和腹侧有两个结节。此外，枢椎腹侧嵴在颅侧部分不太明显，而在尾侧部分变得明显。C3 的棘突是一个宽而小的结节，而 C7 的棘突是垂直延伸的。最后，C6 的横突有一个大的颅腹侧结节，形成一个矢状板，其颅侧和尾侧部分由一个切迹分开。
本研究获得的准确、全面的标准范围可用于解释影像学结果、临床决策以及发现波斯猫颈椎及其突起的正常和异常大小。
