Low-field magnetic resonance imaging and cross-sectional anatomy of the rabbit head

摘要

The purpose of this study was to provide a detailed anatomical description of the soft-tissue structures of the head of normal rabbits using low-field magnetic resonance imaging (MRI). The cadaver heads of six domestic rabbits and one dwarf rabbit were used to perform transverse, sagittal and dorsal 2.5-mm-thick T1-weighted images. Afterwards, three heads were frozen and sectioned at 4-mm-thick intervals using an electric band saw. The anatomical structures identified on these sections were matched with those present on the corresponding MRI images. The images provided detailed information regarding the soft tissues of the heads. Most of the surrounding bony structures and the dentition could be identified. The results of this study could be used as a guide for evaluation of MRI images of the rabbit head in clinical cases of soft tissue deformations or lesions secondary to dental disorders
