Abstract

Stereoloji, üç boyutlu olan yapıların, iki boyutlu görüntüleri üzerinden hesaplamalar yaparak gerçek özelliklerinin tahmininin yapılabildiği etkili bilimsel bir yöntemdir. Bu çalışmada kedilerin kranial bilgisayarlı tomografi (BT) kullanıla-rak intrakranial hacminin stereolojik olarak belirlenmesi ve dimorfik farklılıklarının ortaya konulması amaçlandı. Çalış-mada 16 adet (8 dişi, 8 erkek) erişkin Van Kedisi kullanıldı. Kullanılan kedilerin kranium’ları, çok kesitli BT cihazı ile tarandı. İntrakranial sınırları belirlenen BT kesitlerinden sistematik rastgele örneklem yöntemiyle 12 kesit görüntüsü alınarak stereolojik hesaplamalar yapıldı. Ayrıca intrakranial bölgenin lineer ölçümleri alındı. Elde edilen sonuçlar de-ğerlendirildiğinde intrakranial hacim değerlerinin cinsiyetler arasında dimorfizm gösterdiği belirlendi (P<0.05). Ölçülen lineer parametreler ve hesaplanan index değerlerinin ise cinsiyetler arası dimorfizm göstermediği belirlendi (P>0.05). Sonuç olarak Van kedilerinin intrakranial hacimlerinin stereoloji yöntemi kullanarak belirlenmesi hem hastalıkların tanı, tespit ve tedavileri açısından klinik bilimlere katkı sağlayacağı hem de farklı metotlarla hesaplanan hacim değerlerinin karşılaştırılmasına imkan sağlayacağı düşünülmektedir.

Calculation of Intracranial Volume in Van Cats by Stereological Method

Abstract

Stereology is a powerful scientific method for estimating the real attributes of three-dimensional structures using calculations on two-dimensional photographs. The goal of this study was to determine the cerebral volume of cats using stereological cranial computed tomography (CT) and to uncover dimorphic differences. The study employed 16 adult Van cats (8 females and 8 males). A multislice CT equipment was utilized to scan the craniums of the cats involved in the study. Stereological computations were performed using 12 section images from cranial CT sections with intracranial borders calculated using a systematic random sampling procedure. Linear measurements of the intra-cranial region were also taken. When the findings were analysed, it was discovered that intracranial volume values differed across sexes (P<0.05). It was determined that the measured linear parameters and calculated index values did not show dimorphism between the sexes (P>0.05). As a result, it is thought that the determination of the intracranial volumes of Van cats using stereology method will contribute to clinical sciences in terms of diagnosis, detection and treatment of diseases and will allow the comparison of volume values calculated with different methods.
