ملخص البحث
The current study was designed to describe the normal structures of the head region in sheep
using magnetic resonance imaging (MRI) and cross-sectional anatomy. Eight fresh heads of
adult sheep of both sexes were used; two were scanned using MRI scanner with a 1.5 tesla
magnet, and six fresh heads (n = 6) were frozen at -14oC to be sectioned into transverse (n =
4) and sagittal (n = 2) sections. The accessed MR images were serially matched to the
corresponding gross sections for a comprehensive visualization of the relevant anatomical
structures. The anatomical structures; bones, teeth, cartilages, muscles, membranes, nasal
sinuses and meatuses exhibited variable intensities using T1- and T2-weighted MRI
sequences. Moreover, the white and grey matter of the brain and cerebrospinal fluid were
clearly outlined in T1- and T2-weighted MRI. The present study provided a normal anatomic
reference of the head region of sheep using MRI to be used as a guide for further clinical
diagnosis.
