Computed tomography and normal cross sectional anatomy of the head of the sheep

ABSTRACT

The objective of the present study was to define the detailed description of the anatomy of the head in the native sheep breed in Egypt by computerized tomography [CT] for use by radiologists and veterinary clinicians. Normal five heads of adult sheep of different ages [2-4 years] and sexes [three females and two males] were used in this study. Sheep were killed and the heads were sectioned at the level of atlantoaxial joint. 10-mm contiguous transverse CT images were acquired with a third-generation CT scanner. Frozen cross-sectional slices of sheep head were photographed and compared with the CT images. The important anatomic structures were revealed, seen clearly and labeled in two corresponding photographs of cross-sections and CT scans of the sheep head. The various dimensions of the nasal, cranial and tympanic cavities were recorded
