Ceylanlarda (Gazella subgutturosa) Bilgisayarlı Tomografi Görüntülerini Kullanarak Columna Vertebralis’in Üç Boyutlu Modellemesi ve Morfometrik Analizi

Abstract

Bu çalışma, ceylanlarda multidedektör bilgisayarlı tomografi (MDCT) tarayıcı verilerini kullanarak columna vertebralis’in üç boyutlu (3B) görüntülerini oluşturmak ve bölgenin ayrıntılı anatomik yapısını değerlendirmek için yapıldı. Çalışmada 10 yetişkin (5 erkek ve 5 dişi) ceylan kadavrası kullanıldı. Ceylanlar, 64-dedektörlü MDCT (General Electric Revolution) cihazı ile 80 kv, 200 MA, 639 mGY ve 0.625 mm kesit kalınlığında tarandı. MDCT’den elde edilen kaynak görüntüler, MIMICS 20.1 (The Materialize Group, Leuven, Belçika) yazılımı ile 3B modellere dönüştürüldü. Üç boyutlu modeller üzerinde yapılan incelemede; boyun, sırt, bel, sağrı ve kuyruk omurları sayısı sırasıyla 7, 13, 6, 5 ve 12-16 olarak tespit edildi. Sırt omurlarının yüzey alanı dişilerde ortalama 38096.52±1415.85 mm2, erkeklerde ise 51927.02±4185.70 mm2 olarak tespit edildi. Sırt omurlarının yüzey alanı açısından cinsiyetler arasındaki fark istatistiksel olarak anlamlı bulundu (P<0.05). Elde edilen bulguların ceylan omurgasının diğer türlerle olan farklılıkları veya benzerliklerinin tespitine ek olarak anatomi, cerrahi ve zooarkeoloji alanında yapılacak daha ileri çalışmalarda referans veriler sağlayacağı değerlendirilmektedir.

Three-Dimensional Modelling and Morphometric Analysis of the Vertebral Column in Gazelles (Gazella subgutturosa) by using Computer Tomographic Images

Abstract

This study was performed to create three-dimensional (3D) images of gazelles’ vertebral column bones using two-dimensional multi-detector computed tomography (MDCT) outputs and to evaluate detailed anatomical structure of the region. In the study, 10 adult (5 males and 5 females) gazelle cadavers were used. Materials were scanned under 80 kv, 200 MA, 639 mGY and 0.625 mm section thickness using a 64-detector MDCT (General Electric Revolution). The MDCT outputs were converted into 3D formats with MIMICS 20.1 (The Materialise Group, Leuven, Belgium) software. Numbers of the cervical, thoracic, lumbar, sacral and caudal vertebra were detected as 7, 13, 6, 5 and 12-16, respectively. The surface area of thoracic vertebrae was found to be 38096.52±1415.85 mm2 in females and 51927.02±4185.70 mm2 in males. The difference between the genders in terms of surface area of thoracic vertebrae was found to be statistically significant (P<0.05). It is considered that the findings obtained will provide reference data for further studies in anatomy, surgery and zooarchaeology in addition to determining differences or similarities of gazelle vertebral column with other species.
