Kangal Köpeklerinde Trachea’nın Bilgisayarlı Tomografi ile Üç Boyutlu Değerlendirilmesi

Abstract

Bu araştırma; Kangal köpeklerinde ilk kez bilgisayarlı tomografik görüntüler kullanılarak trachea’nın ayrıntılı anatomisini elde etmek amacıyla gerçekleştirilmiştir. Çalışmada 5 erkek ve 5 dişi olmak üzere toplam 10 erişkin Kangal köpeği kullanılmıştır. Multidedektör bilgisayarlı tomografi (MDBT) cihazından elde edilen görüntüler, üç boyutlu (3D) modelleme yazılımı (VITAL, Vitrea 2,HP XW 6400) ile trachea’nın üç boyutlu yeniden yapılandırılmasında kullanılmıştır. Trachea’nın ölçümleri; hem pars cervicalis hem de pars thoracalis bölgelerinde; cranial ve caudal noktalar belirlenerek yapılmıştır. Trachea’nın 4 noktasından alınan transversal ve vertical çap ölçümleri, bu çapların birbirlerine oranı (T/V) ile kesitsel lümen alanları (crosssectional area CSA), BT (Bilgisayarlı tomografi) tarayıcı yazılımı ile ölçülmüştür. Erkekler ve dişiler arasında önemli bir istatistiksel fark bulunmamıştır. Trachea’nın başlangıç ve bitiş kısımlarında çapların arttığı gözlenmiştir. Transversal çapların bütün ölçüm noktalarında vertical çaplardan daha yüksek değerlerde olduğu tespit edilmiştir. Üç boyutlu modelleme ile trachea’nın dorsoventral basık ve tam olmayan elipsoid şeklinde olduğu ortaya konmuştur. Araştırmanın ilk kez yapılmış olması sebebiyle, anatomi alanındaki benzer çalışmalara kaynak teşkil edebileceği düşünülmektedir.

Three Dimensional Evoluation of Trachea with Computed Tomography in The Kangal Dogs

Abstract

This study was conducted to obtain a detailed anatomy of the trachea in Kangal dogs, for the first time using computerized tomographic images. In this study, 5 male and 5 female total 10 adult Kangal dogs were used. The images obtained from a multidetector computerized tomography device (MDBT) were used for 3D reconstruction of the trachea with the 3D modelling software (VITAL, Vitrea 2, HPXW 6400). The measurements of the trachea were made from the cranial and caudal points determined at the cervical and thoracal regions. Transversal and vertical diameters of the trachea taken from 4 different points , the ratio of these diameters (T/V) and cross sectional areas (CSA) , were measured by CT (computer tomography) scanner software. A significant statistical difference was not found between males and females. An increase in the diameter of the trachea at the beginning and terminal parts was observed. It was found that the transversal diameters were greater than the vertical diameters at all measuring points. In the 3D modelling, trachea has been found to be dorsoventrally flat with an incomplete elipsoid form. It is thought that this work, which was first made in Kangal dogs, may be a source for similar work in the anatomy.
