Abstract

The
purpose of the study was to scan the brain and related structures in sheep with
high-resolution magnetic resonance
imaging (MRI) and three-dimensional (3D)
multiplanar reconstruction for defining
the anatomical regions. Six adult sheep, three of six were male and three of
six were female used as cadaver, were utilized in this research. Heads were
scanned at 3 Tesla Siemens Magnetom Spin-Echo MRI devices using the human head coil. The processes were acquired in
both T1 and T2 weighted slices and were reconstructed by using Leonardo
workstation. The cranioencephalic structures and anatomical details were
defined and labeled in all slice of 3 planes that were obtained 1 mm thickness
sequential images in sagittal, frontal, and transversal planes. According to
the MRI measurements obtained intracranially from the brain, the average value of length, height, and width of the brain were 87.1 ± 0.3, 46.8 ± 0.7, and 62.2 ± 0.4
mm, respectively. It was observed that in T1 weighted images were more
effective to identify deep brain structures and anatomical details. On 3D
reconstructed images obtained from the study can be used as a reference in head
and brain MR scans in multidisciplinary studies where sheep are used as animal
models.
