چکیده
هدف از این مطالعه بررسی مورفولوژی و مورفومتری مهره‌های گردنی خوکچه‌هندی (Cavia porcellus) بر اساس تصاویر توموگرافی کامپیوتری (CT) بود. در این مطالعه از 10 سر خوکچه‌هندی سالم (5 نر و 5 ماده) استفاده شد. متعاقب بی‌هوشی هر خوکچه‌هندی، سی‌تی‌اسکن از ابتدای مهره اطلس تا انتهای مهره هفتم گردنی آن در پلن‌های عرضی، ساجیتال و دورسال انجام گرفت. بر اساس یافته‌های این مطالعه، بال‌های مهره اطلس خوکچه‌هندی پهن بوده و هر بال دارای یک سوراخ جانبی است که در پلن دورسال CT بهتر قابل مشاهده است. در قسمت میانی بریدگی آلار این مهره، شیاری دیده می‌شود که به سوراخ جانبی منتهی می‌شود. این یافته برای اولین‌بار گزارش می‌گردد و می‌تواند مبین آناتومی مقایسه‌ای این حیوان با سایر گونه‌های جوندگان مانند موش سوری و موش صحرایی باشد. در تصاویر ساجیتال و دورسال CT، زائدة ادونتوئید مهره آسه به‌صورت یک برجستگی طویل و گرد دیده می‌شود. زائده عرضی مهره C6 دارای یک برآمدگی شکمی وسیع و یک قسمت پشتی کوچک‌تر است که توسط یک بریدگی از هم جدا می‌شوند. این ویژگی خاص مهره C6 در آناتومی مقایسه‌ای این‌گونة جانوری مطرح می‌گردد. مهره C3 کمترین و مهره C7 بیشترین  VH را در بین مهره‌های گردنی دارند (05/0P≤). مقدار پارامترهای TDCrVF و VDCrVF در مهره اطلس بیش از سایر مهره‌ها است (05/0P≤). یافته‌های این تحقیق می‌تواند در آموزش آناتومی توموگرافی کامپیوتری مهره‌های گردنی خوکچه‌هندی، تفسیر تصاویر سی‌تی‌اسکن و نیز در معاینات بالینی و امور درمانی این حیوان خانگی مورد استفاده قرار گیرد.

چکیده English

This study aimed to investigate the morphology and morphometry of the cervical vertebrae of guinea pigs (Cavia porcellus) based on computed tomography (CT) images. In this descriptive cross-sectional study used 10 healthy guinea pigs (5 males and 5 females). Following anesthesia of each guinea pig, CT scans were performed from the beginning of the atlas vertebra to the extremity of the seventh cervical vertebra in the transverse, sagittal, and dorsal planes. According to the findings of this study, the wings of the atlas vertebra are wide and each process has a lateral foramen that is better visible in the dorsal plane. In the middle of the alar notch of this vertebra, a groove is visible that leads to the lateral foramen of this vertebra. The odontoid process or dens of the C2 vertebra is seen as an elongated, rounded protrusion on sagittal and dorsal CT images. The transverse process of the C6 vertebra has with ventral portion and a dorsal portion separated by a notch. The C3 and C7 vertebrae had the lowest and highest VH respectively (P≤0.05). The values ​​of TDCrVF and VDCrVF parameters in the atlas vertebra were higher than in other vertebrae (P≤0.05). The findings of this study can be utilized to the teaching of computed tomographic anatomy of the cervical vertebrae of the guinea pig, the interpretation of CT scan images, as well as performing clinical and treatment examinations this lovely pet.
