Ceylanlarda (Gazella subgutturosa) Intracranial Hacmin Stereoloji ve Bilgisayarlı Tomografi ile Hesaplanması

Abstract

The danger of extinction faced by the gazelles, which show a broad geographical distribution, in recent times and inclusion of the gazelles in the conservation list of IUCN indicate the importance and necessity of the studies on continuity of the species. In this context, the determination of intracranial volume is clinically essential for the breed and sexual dysmorphism. In the present study the crania of 11 gazelles (5 male and 6 female gazelles) (Gazella subgutturosa) were used. The cranium of the gazelles were scanned at 80 kV, 200 mA, 639 mGY, and 0.625 mm section thickness using 64‐slice Multi‐Detector Computed Tomography (MDCT). The intracranial volume of the gazelles was estimated using computed tomography sections according to Cavalieri’s Principle. Three‐dimensional models of the intracranial area were created using MIMICS 20.1 Software, the software calculated intracranial volume. The obtained results were statistically tested in terms of both methods and sexual dimorphism. The study results revealed that crania showed no difference between sexes (P>0.05). No difference was detected between the two methods in statistical analysis of the intracranial volumes calculated using stereology and CT models. Consequently, it was considered that the use of intracranial volumes of the gazelles would contribute to the clinical sciences concerning detection, diagnosis and progression of the diseases.
