Abstract

Son yıllarda, anatomi alanında 3 Boyutlu (3B) tarayıcılar ve bilgisayarlı tomografi kullanan çalışmaların sayısında belirgin bir artış olmuştur. Ancak literatürde, bu iki yöntem arasındaki uyumluluğu değerlendiren çalışmaların sınırlı olduğu gözlenmiştir. Yapılan çalışmada toplam 12 yetişkin tavşan kullanılmıştır. Maserasyonun ardından, seçilen ekstremite kemikleri hem bilgisayarlı tomografi (BT) hem de 3B tarayıcı kullanılarak 3B rekonstrüksiyona tabi tutulmuştur. Elde edilen modeller, morfolojik olarak analiz edilmiştir. Scapula’da, acromion’un ventral ucunun proc. hamatus'ta sonlandığı ve metacromion olarak caudal olarak uzandığı gözlemlendi. Humerus’ta, tuberculum majus’un caput humeri'yi hafifçe aştığı ve distal uçta foramen supratrochleare gözlendi. Önkol iskeleti radius ve ulna’dan oluştuğu ve ulna’nın daha gelişmiş olduğu gözlendi. Radius, belirgin bir fovea capitis radii ve proc. styloideus radii sahipken, ulnae’da belirgin bir tuber olecrani ve processus styloides ulnae varlığı tespit edildi. Femur’da, trochanter major’un caput femoris düzeyini aştığı ve crista intertrochanterica trochanter major ile trochanter minor arasında yer aldığı gözlendi. Distal femurda, facies poplitea belirgindi. Ossa cruris, tek bir yapı halinde birleşmiş tibia ve fibula şeklinde olduğu tespit edildi. Sonuç olarak, her iki yöntemle oluşturulan 3B modellerde belirlenen anatomik noktalar benzerlik göstermekteydi. CT, tüm dokuları tarama ve hızlı veri sağlama konusunda üstünlük sağlarken, 3B tarayıcılar taşınabilirlik, renkli görüntüleme ve maliyet açısından avantajlar sunmaktadır. Yöntemlerin birlikte kullanılması, veteriner anatomi eğitimi için faydalı olabileceği düşünülmektedir.

3D Reconstruction of Some Limb Bones in New Zealand Rabbits with 3D Scanning and Computed Tomography: Morphological Investigation

Abstract

In recent years, there has been a notable increase in the number of studies utilizing three-dimensional (3D) scanners and computed tomography in the field of anatomy. However, the literature reveals that studies evaluating the compatibility between these two methods remain limited. In this study, a total of 12 adult rabbits were used. Following maceration, selected limb bones were subjected to 3D reconstruction using both computed tomography (CT) and 3D scanner. The resulting models were analyzed morphologically. On the scapula, the ventral end of the acromion was observed to terminate at the proc. hamatus and extend caudally as the metacromion. In the humerus, the tuberculum majus slightly surpassed the caput humeri, and a foramen supratrochleare was present at the distal end. The antebrachial skeleton consisted of the radius and ulna, with the ulna being more developed. The radius displayed a distinct fovea capitis radii and processus styloideus radii, while the ulna exhibited a prominent tuber olecrani and a proc. styloideus ulnae. The femur, the trochanter major extended beyond the femoral head, with the crista intertrochanterica located between the trochanter major and trochanter minor. At the distal femur, facies poplitea were clearly visible. The crural skeleton consisted of the tibia and fibula, which were fused into a single structure. In conclusion, the anatomical landmarks identified in the 3D models generated by both methods were consistent. While CT excels in scanning entire tissues and providing rapid data, 3D scanners offer advantages portability, color imaging, and cost. Combined use of methods is considered beneficial for veterinary anatomy education.
