Computed Tomographic Imaging Characteristics of the Thyroid Glands in Clinically Normal Van Cats
Öz: This study was performed to obtain morphometric and volumetric measurements of thyroid glands of Van Cats, and to determine homotypical variations and biometric differences between the genders. Thyroid gland computed tomography (CT) images obtained from a total of 16 clinically healthy adult Van Cats (8 males, 8 females) were used in the study. Measurements were made on the transverse, sagittal, and dorsal sections of both right and left thyroid gland CT images. Volumes of the thyroid lobes were estimated using transverse ellipse, maximum ellipse, and planimetry methods. Statistical analyses were then performed on the obtained morphometric and volumetric values. In terms of sexual dimorphism in Van Cats, morphometric and volumetric measurement values of the thyroid gland were found to be larger in male cats than in females (P<0.05). When the parameters were inspected in terms of homotypical variations, measured values for the right thyroid lobes were found to be larger compared to the left thyroid lobe values in both male and female cats. Average length, width, height values for male thyroid glands were 25.41±1.63 mm, 2.49±0.09 mm, and 4.54±0.21 mm, respectively, while the same values were 19.57±0.92 mm, 2.06±0.17 mm, and 4.19±0.21 for female cats, respectively. Average thyroid gland volumes calculated through transverse ellipse, maximum ellipse, and planimetry values were 149.46±19.71 mm3, 154.80±19.70 mm3, and 166.86±19.04 mm3 for males, respectively. The female counterparts for these values were 89.52±11.82 mm3, 92.31±11.90 mm3, 109.40±6.02 mm3, respectively. As a result, various parameters on CT images of thyroid glands in clinically healthy Van Cats were measured and the results were statistically evaluated between the genders. It is thought that the results will be useful in the evaluation of abnormal thyroid glands in Van Cats CT images in clinical practices.

Öz: Bu çalışma, Van Kedilerinde thyroid bezinin morfometrik ve volümetrik ölçülerini elde etmek ve bu ölçüm değerlerinin hem homotipik varyasyonlar hem de cinsiyetler arasındaki biyometrik farklılıklarını ortaya koymak amacıyla yapıldı. Çalışmada klinik olarak sağlıklı 16 adet erişkin Van Kedisi (8 erkek, 8 dişi) thyroid bezine ait bilgisayarlı tomografi (BT) görüntüsü kullanıldı. Sağ ve sol thyroid bezine ait transversal, sagital ve dorsal kesitlerden morfometrik ölçümler alındı. Thyroid loblarının hacimleri transversal elips, maximum elips ve planimetri yöntemleri kullanılarak tahmin edildi. Morfometrik ve volümetrik değerlerin istatistiki analizi yapıldı. Van Kedilerinde seksüel dimorfizm bakımından, thyroid bezine ait morfometrik ve volümetrik ölçüm değerlerinin erkek kedilerde dişilere göre daha yüksek olduğu görüldü (P<0.05). Ayrıca, ölçüm parametrelerine homotipik varyasyonlar bakımından bakıldığında ise hem erkek hem de dişi kedilerde sağ loptaki ölçüm değerlerinin sol loba oranla daha yüksek olduğu tespit edildi. Thyroid bezine ait ortalama uzunluk, genişlik ve yükseklik değerleri erkeklerde sırasıyla 25.41±1.63 mm, 2.49±0.09 mm ve 4.54±0.21 mm, dişilerde ise bu değerler sırasıyla 19.57±0.92 mm, 2.06±0.17 mm ve 4.19±0.21 mm olarak belirlendi. Transversal elips, maximum elips ve planimetri yöntemleriyle hesaplanan thyroid bezine ait ortalama volüm değerleri erkeklerde sırasıyla 149.46±19.71 mm3 , 154.80±19.70 mm3 ve 166.86±19.04 mm3, dişilerde ise ortalama sırasıyla 89.52±11.82 mm3, 92.31±11.90 mm3 ve 109.40±6.02 mm3 olarak hesaplandı. Sonuç olarak, klinik olarak sağlıklı Van Kedilerinde thyroid bezine ait ölçüm parametrelerinin istatistiksel olarak cinsiyetler arasındaki farklılıkları BT görüntüleri kullanılarak değerlendirildi. Elde edilen verilerin Van Kedilerinde anormal thyroid bezine ait BT görüntülerinin değerlendirilmesinde faydalı olacağı düşünülmektedir.
