Öğe Analysis of the correlation between thyroid hormones and thyroid volume by gender: A volumetric computed tomography study(2022) Öner, Zülal; Öner, Serkan; Secgin, Yusuf; Toy, ŞeymaThe aim of this study was to evaluate the correlation between triiodothyronine (T3), thyroxine (T4), and thyroid-stimulating hormone (TSH) hormones and thyroid gland volume with volumetric analysis performed by using computed tomography (CT) images. In this retrospective study, IV contrasted thoracic CT images taken for different indications between 2019 January and 2020 January were scanned from the archive system of the hospital. 67 (31F, 36M) individuals chosen randomly among patients whose CT results were reported as normal and who had taken thyroid hormone tests within the past week were included in the study. Images in Digital Imaging and Communications in Medicine format were transferred to the personal work station program (Horos Medical Image Viewer). By using the Region of Interest (ROI) console in the current program, a three dimensional model was obtained by drawing the border of the thyroid gland in sections varying between 15 and 25. Volume values of this three-dimensional model and TSH, T3, T4 values of the individuals were compared. While no correlation was found between thyroid gland volume and T3 and T4 hormones, a negative significant correlation was found with TSH. In terms of gender, thyroid gland volume, T3, T4 values were found to be statistically significantly higher in women when compared with men (p?0.05). TSH value was found to be higher in women when compared with men (p=0.005). No statistically significant difference was found in T4 value (p=0.057). Radio-anatomical volumetric data of the thyroid gland presented in this study and its correlation with thyroid functions will be beneficial to clinicians working in the field in both internal and surgical medicine branches and will also guide future studies.Öğe Associating craniofacial morphometry determined by photo analysis with somatotype in healthy young individuals(2023) Toy, Şeyma; Şenol, Deniz; Öner, ZülalObjectives: Evaluation of the relationship between craniofacial parameters and somatotype provides important contributions to specialist physicians and anatomists in determining diseases and obtaining objective results of anthropometric measurements. The study was designed in line with this hypothesis and the aim was to find out how this relationship changed in healthy individuals. Methods: The study was conducted by examining 191 healthy individuals between the ages of 18 and 30. The individuals’ faces were photographed from a distance of 1 meter and craniofacial parameters were measured in Image J program. Somatotype analysis was conducted by using Heath-Carter somatotype method. Results: As a result of our study, the individuals were found to be grouped in four classes according to Heath-Carter somatotype method: (1) mesomorph endomorph, (2) endomorph ectomorph, (3) endomorph mesomorph and (4) central. Significant correlation was found between the second and first somatotype groups in terms of total nasal length, while significant correlation was found between second and first/second and third/fourth and third/first and third somatotype groups in terms of body mass index (BMI) parameter (p < 0.05). Craniofacial parameters were also evaluated and a very high correlation was found between total facial height and mandibular height, while there was a high correlation between total facial height and the other 16 parameters. Conclusions: As a result of our study, a relationship was found between somatotype groups and craniofacial parameters, within craniofacial parameters, and between somatotype and BMI. We believe that this relationship will guide morphological studies in basic medical sciences and surgical interventions in clinical sciences.Öğe Bilgisayarlı Tomografi Görüntüleri Üzerinden Hesaplanan Tibia Parametrelerinin Yaş ve Cinsiyete Göre Değerlendirmesi(Karabük Üniversitesi, 2024) Emiroğlu, Muhammed; Toy, Şeyma; Seçgin, Yusuf; Öner, SerkanAmaç: İnsan kalıntılarından kemikler kompakt yapılarından dolayı doğada uzun süre korunur ve bu durum kimliklendirmede kullanışlı olmalarını sağlar. Dimorfizm gösterdiği bilinen kemikler olsa da tibia ve femur erozyona karşı ciddi derecede dirençli olmaları dolayısı ile yaş ve cinsiyet değerlendirmelerinde kullanılabilir. Bu çalışmanın amacı bilgisayarlı tomografi (BT) görüntüleri üzerinden hesaplanan tibia parametrelerinden yaş ve cinsiyetin değerlendirmesidir. Gereç ve yöntem: Bu çalışma 2015-2022 yılları arasında 114 bireye ait alt ekstremite BT anjio görüntülerinin retrospektif olarak incelenmesi ile gerçekleştirildi. Bireyler 30-40 (1. yaş grubu), 41-50 (2. yaş grubu), 51-60 (3. yaş grubu) yaş gruplarına ayrıldı. Görüntüler DICOM formatında Radiant DICOM Viwer programına aktarıldı ve tibia üzerinden Sağ condylus medialis ile lateralis arası uzunluk (CML-RL), Sol condylus medialis ile lateralis arası uzunluk (CML-LL), Sağ tibianın ortasında corpus tibia genişliği (CT-RW), Sol tibianın ortasından corpus tibia genişliği (CT-LW), Sağ condylus medialis-malleolus medialis arası uzaklık (CMMM-RL), Sol condylus medialis-malleolus medialis arası uzaklık (CMMM-LL), Sağ condylus lateralis-malleolus lateralis arası uzaklık (CLML-RL), Sol condylus lateralis-malleolus lateralis arası uzaklık (CLML-LL), Sağ malleolus medialis-tuberositas tibia-malleolus lateralis arası açı (MMTML-RA), Sol malleolus medialis-tuberositas tibia-malleolus lateralis arası açı (MMTML-LA) parametrelerin ölçümleri gerçekleştirildi. Bulgular: Kruskal Wallis H testi ile yaş grupları karşılaştırıldı ve sol condylus medialis ile lateralis arası uzunluk parametresinde 1. ile 2. yaş grubu arasında sağ condylus medialis-malleolus medialis arası uzaklık parametresinde 1. yaş grubu ile diğer yaş grupları arasında, sol condylus medialis-malleolus medialis arası uzaklık parametresinde 1. ile 3. yaş grubu arasında, sağ condylus lateralis-malleolus lateralis arası uzaklık parametresinde 1. yaş grubu ile diğer yaş grupları arasında istatistiksel olarak anlamlı ilişki olduğu bulundu. One Way Anova testi ile sol condylus medialis-malleolus medialis arası uzaklık parametresinde 1. ve 3. grupları arasında anlamlı ilişki bulundu. Sol condylus medialis ile lateralis arası uzunluk (CML-RL, LL) hariç tüm parametrelerde cinsiyetler arasında istatistiksel olarak anlamlı fark olduğu sonucuna ulaşıldı (p<0.05). Sonuç: Çalışmamız sonucunda erozyona karşı dirençli olan tibia’dan belirlediğimiz parametrelerin yaş ve cinsiyeti belirlemede önemli belirteçler olduğu belirlendi. Bu yönüyle hem literatürdeki çalışmalara hem de yeni yapılacak çalışmalara katkı sağlayacağı kanaatindeyiz.Öğe Correlation of Morphometric Parameters Taken from the Head of the Mandible with Other Parameters of the Mandible(2022) Toy, Şeyma; Seçgın, Yusuf; Şenol, Deniz; Öner, Zülal; Ray, Abdullah; Malkoç, İsmailBackground: The mandible is a very important bone for forensic medicine, anthropology, anatomy and odontology sciences. This bone has many functions such as speaking, chewing and swallowing. This study was carried out to examine the relationship between morphometric parameters ob-tained from the head of the mandible and other parameters of the mandible.Materials and Methods: In our study, 45 dry mandible bones were used. These bones were photo-graphed and measured in the Image J program. These measurements were the distance of the head of the mandible to mental foramen (right, left), the distance of the head of the mandible to angle of the mandible (right, left), the distance of the head of the mandible to gnathion (right, left), the distance of the head of the mandible to coronoid process (right, left), the distance of the head of the mandible to the mandibular notch (right, left), the distance of the head of the mandible to alveolar juga (right, left) and the distance between right and left head of the mandible.Results: While no difference was found in terms of direction in dry mandibles with correlation anal-ysis (p>0.05), a high significant correlation was found in 18 parameters (p≤0.05).Conclusions: In our study, correlations were found between parameters obtained from the head of the mandible and other parameters of the mandible.Öğe Evaluation of the Differences in Parameters Obtained from the Computed Tomography Images of the Eyeball and the Structures in the Orbit by Age and Gender(2024) Akyer, Nurhan; Toy, Şeyma; Seçgin, Yusuf; Şenol, Deniz; Öner, Serkan; Oner, Zulal; Turan, Muhammed KamilObjective: The aim of this study is to show the variation of eyeball and orbital structures according to different age groups and gender. Method: The study was conducted on computerized tomography (CT) images of 4 age groups: 30-40, 41-50, 51-60, and over 61 years old. The parameters were, the angle between the optic nerve and axis of eyeball (A-Cr2AA), the length of the medial rectus muscle (MRML) and the length of the lateral rectus muscle (LRML) up to the Zinn ring, the thickness of the lens (LT), the length of the optic nerve from the Zinn ring (Cr2L), optic nerve thickness (Cr2T), distance between two eyeballs (BOD) and the others. Results: As a result of the study, in the comparison of males in four groups, significant difference was found between the groups in LT, Cr2L, A-Cr2AA, MRML parameters in the right eyeball and Cr2L and LRML parameters in the left eyeball (p<0.05). In the comparison of females in four groups, significant difference was found between the groups in BOD, LT, Cr2L, LRML, MRML in the right and left eyeball and Cr2T parameter in the left eyeball (p<0.05). Conclusion: As a result of the study, it was determined that age and gender differed in the determined parameters.
