In this study, magnetic resonance (MR) images of the brain of an adult common dolphin (Delphinus delphis) were acquired in the coronal plane at 66 antero-posterior levels. From these scans a computer-generated set of resectioned virtual images in orthogonal planes was constructed using the programs VoxelView and VoxelMath (Vital Images, Inc., Michigan State Univ.). Sections in all three planes reveal major neuroanatomical structures. These structures in the adult common dolphin brain are compared with those from a fetal common dolphin brain from a previously published study as well as with MR images of adult brains of other odontocetes. This study, like previous ones, demonstrates the utility of MR imaging (MRI) for comparative neuroanatomical investigations of dolphin brains.
在本研究中，对一只成年普通海豚（瓶鼻海豚）的大脑进行了磁共振（MR）成像，在冠状面获取了66个前后层面的图像。利用VoxelView和VoxelMath程序（Vital Images公司，密歇根州立大学），从这些扫描图像中构建了一组计算机生成的正交平面上的虚拟切除图像。三个平面的切片均显示出主要的神经解剖结构。将成年普通海豚大脑中的这些结构与先前发表的一项研究中一只胎儿普通海豚大脑的结构以及其他齿鲸成年大脑的MR图像进行了比较。与之前的研究一样，本研究证明了磁共振成像（MRI）在海豚大脑比较神经解剖学研究中的实用性。
