The intracranial cavity contains vitally important organs. The brain, cerebellum, meninges and the vessels that supply these organs are located in the intracranial cavity. Therefore, it is important to learn about the intracranial cavity and to study it. However, there is limited information about the intracranial cavity in the veterinary field. The aim of this study was to determine the differences between the intracranial cavities of different species of animals by using stereology and tomography methods, volume calculations and morphometric measurements. In addition, the compatibility of the methods used with each other was investigated. In the study, six male adult goats and six male adult sheep were used. In this study, the intracranial cavities of sheep and goats were calculated by using Cavalieri's principle and 3D modelling using tomography sections. Morphometric measurements were taken over the intracranial space, and index calculations were made. In 3D models using computed tomography, the intracranial volume was 153.31 ± 24.06 cm in goats and 128.07 ± 7.93 cm in sheep. In the calculation using Cavalieri's principle, it was determined to be 152.73 ± 22.73 cm in goats and 126.15 ± 8.38 cm in sheep. As a result of the study, the MWCC (maximum width of the cranial cavity) parameter was found to be statistically significant between species (p < 0.05). The two methods used in Bland-Altman analysis were found to be within the limits of agreement, and the methods can be alternative to each other.
颅内腔包含至关重要的器官。大脑、小脑、脑膜和为这些器官供血的血管都位于颅内腔。因此，了解和研究颅内腔非常重要。然而，兽医领域关于颅内腔的信息有限。本研究旨在通过体视学法和断层扫描法、体积计算和形态测量学来确定不同动物物种颅内腔的差异。此外，还研究了所使用的方法之间的兼容性。在研究中，使用了六只雄性成年山羊和六只雄性成年绵羊。在本研究中，通过 Cavalieri 原理和使用断层扫描切片进行 3D 建模计算了绵羊和山羊的颅内腔。对颅内空间进行了形态测量，并进行了指数计算。在使用计算机断层扫描的 3D 模型中，山羊的颅内体积为 153.31 ± 24.06 cm，绵羊的颅内体积为 128.07 ± 7.93 cm。在使用 Cavalieri 原理的计算中，山羊的颅内体积为 152.73 ± 22.73 cm，绵羊的颅内体积为 126.15 ± 8.38 cm。研究结果表明，MWCC（颅腔最大宽度）参数在物种间具有统计学意义（p < 0.05）。 Bland-Altman 分析中使用的两种方法均在一致性界限内，并且可以相互替代。
