Neuroanatomy of the calf brain as revealed by high-resolution magnetic resonance imaging.

摘要: Here, we want to assess the benefit of high-resolution and high-contrast magnetic resonance imaging (MRI) for detailed documentation internal brain morphology in formalin-fixed whole head specimens full-term calf (Bos taurus). Imaging was performed on a Siemens 1.5 T scanner. Optimum contrast achieved using 3D sequence with flip angle 30°, repetition time (TR) 20 ms, echo (TE) 6.8 an interpolated matrix 1024 × 1024. In plane resolution 0.25 mm. Computer-generated three-dimensional images were reconstructed from original scans coronal plane. This study shows that MRI is capable identify delicate structures immature specimens. The use comparative facilitates examination series brains or samples reasonable time. comprehensive description species- group-specific features Bos taurus will complement existing data diagnostic neuromorphological research, general, as well phylogenetic reconstructions.
