    Assessing Thoracic Symmetry in Dogs
    (Univ Agriculture, Fac Veterinary Science, 2024) Mutlu, Zihni; Altundag, Yusuf; Guzel, Baris Can
    This study aimed to conduct a detailed statistical shape analysis of the thorax across various dog breeds, focusing on the identification and characterization of shape variations and asymmetrical features. For this purpose, 3D images of 39 thoracic samples were collected from various regions across T & uuml;rkiye, ensuring a diverse representation of breeds and populations. In the analysis, 136 specific anatomical landmarks were meticulously identified and marked from a lateral view of the thorax for each sample. The study revealed that the first principal component explained 28.89% of the total variation in directional asymmetry, suggesting consistent size or shape differences on one side of the thorax. Additionally, it was found that the first principal component explained 27.82% of the total variation in fluctuating facet asymmetry occurs if one region is consistently greater or has a different shape compared to the opposite and indicates underlying genetic or functional differences. This study highlights the usefulness of geometric morphometric analysis in distinguishing thoracic shape differences among various dog breeds, providing insights into their morphological diversity. Moreover, the findings underscore the potential of geometric morphometric analysis for taxonomic purposes, enabling more precise classification and understanding of breed-specific characteristics. This approach can aid in identifying subtle morphological variations that may be linked to breed history, function, or environmental adaptation.

    Examination of the Vertebral Heart Scale and Anatomical Structure of Different Dog Breeds by Computed Tomography
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2024) Yaramis, Cagla Parkan; Erdikmen, Dilek Olgun; Altundag, Yusuf; Ozkan, Ermis; Guzel, Barks Can
    This study aims to reveal the statistical difference by measuring the vertebral heart scale and anatomical structures of the heart in different dog breeds. The vertebral heart scale (VHS) has recently been described as a method for measuring the heart silhouettes of dogs and cats. Vertebral heart scale (VHS) may vary in dog and cat breeds due to age, weight, etc. Twenty-one dogs (10 males and 11 females) of different ages and weights were used. Among the dog breeds used are the French Bulldog, Russian Poodle, Rottweiler, Jack Russell, Golden Retriever, King Charles, Pekingese, Belgian Shepherd, Husky, Chihuahua, Cocker, Terrier, Bulldog, Bouvier and Flanders breeds. Multislice detectors were scanned at 80 kV, 200 MA, 639 mGY, and 0.625 mm slice thickness. The resulting images were saved in Digital Imaging and Communications in Medicine (DICOM) format. The obtained sections were measured in 3D-Slicer software. Thoracic height (TH) and cranial vena cava (CVC) measurement parameters were statistically significant with weight (P<0.05). Vertebral heart scale (VHS) was not statistically significant with any parameter in the correlation analysis (P>0.05). At the correlation table of animal weight with the measurements, it was seen that it had a very significant positive correlation with other measurement parameters except vertebral heart score (VHS) (P<0.01). Vertebral heart scale was determined as 9.09 +/- 1.37 vertebrae in females and 9.50 +/- 0.52 vertebrae in males. The study aims to contribute to veterinary anatomy, surgery and internal medicine.
