Abstract
Background: Computed tomography (CT) is one of the most practical and accurate diagnostic imaging techniques to evaluate bones and joints in small animals.
Objectives: The present study aimed to investigate the morphology and osteometric measurements of the Persian cat’s antebrachium bones based on CT images.
Methods: This cross-sectional descriptive study was conducted on 10 healthy adult Persian cats (5 males and 5 females). The anesthetized Persian cat was placed in a dorsoventral position on the CT scanner table with its forelimbs fully extended, and sagittal, transverse, and dorsal scans were performed from the proximal extremity of the metacarpals to the distal third of the humerus.
Results: Based on the study results, CT provides the possibility of identifying most of the anatomical structures of the forearm area of the Persian cat. In the CT images, the bones appeared white due to their high density, and their medullary cavities were dark. Additionally, muscles and tendons were visible on different gray scales. The structural details of the joint between the proximal extremity of the radius and the capitulum of the humerus and the joint between the distal extremity of the radius and the radial carpal bone could be better evaluated in the transverse CT plane. Proximal radioulnar and radiohumeral joints were examined better in transverse and sagittal CT plans. All details related to the olecranon, anconeal, and coronoid processes were visible in sagittal, transverse, and dorsal CT reconstructions. The structural features of the joint between the semilunar notch and trochlea of the humerus were more visible in the dorsal CT plane. Based on transverse CT images, the thickness of the cortex and the internal diameter of the medullary cavity of the radius and ulna bones were measured and statistically analyzed.
Conclusion: The results of this research indicate that the anatomical structures of the antebrachium bones of Persian cats are similar to those of other domestic cats. The study findings can be utilized in the teaching of computed tomographic anatomy, the interpretation of CT scan images, and performing clinical and treatment examinations of this breed of cat.
