Stereological and computed tomography calculation of intracranial volume in Hamdani sheep

Abstract

AbstractThe intracranial cavity contains vital organs such as the brain, cerebellum and meninges. The veterinary field employment in this region is limited. For this reason, obtaining information about the intracranial cavity, the operation to be performed on this region and information about the world will benefit our unit. It aimed to examine the width between gender differences and expectations by calculating the intracranial volume stereological and 3D models using computed tomography sections. In the study, 7 male and 6 female adult Hamdani sheep were used. The intracranial cavity was modelled in 3D using computed tomography sections. Intracranial volume was estimated using CT slices according to the Cavalieri principle. Morphometric measurements were obtained from the intracranial cavity. In the study, intracranial volume was calculated as 120.50±7.59 cm3 in females and 137.29±9.79 cm3 in males in measurements made using Computed Tomography. Intracranial volume calculation made using the Cavalieri's principle was calculated as 125.33±5.20cm3 in females and 136.89±9.13 cm3in males. In the configured CT models, a target difference was detected between the male and female volume values calculated on it (p < 0.05). There was a difference between males and females in stereologically viable intracranial volume (p < 0.05). A high level of density was observed between the results of both methods. In the mean of the data, there was no difference between the objectives (p > 0.05). Morphometric measurements determined that the maximum cranial cavity width parameter was between females and males (p < 0.005). In index1 and index2 calculated with the obtained partitions, a circulating difference between genders was observed (p < 0.05). In the resulting state, the 3‐dimensional intracranial cavity models and the intracranial volume fraction estimated by the Cavalieri principle are conserved. There are high limits between the methods. Feeding future intracranial volume and clinical care.
