This study was performed to anatomically illustrate the living canine hippocampal formation in three-dimensions (3D), and to evaluate its relationship to surrounding brain structures. Three normal beagle dogs were scanned on a MR scanner with inversion recovery segmented 3D gradient echo sequence (known as MP-RAGE: Magnetization Prepared Rapid Gradient Echo). The MRI data was manually segmented and reconstructed into a 3D model using the 3D slicer software tool. From the 3D model, the spatial relationships between hippocampal formation and surrounding structures were evaluated. With the increased spatial resolution and contrast of the MPRAGE, the canine hippocampal formation was easily depicted. The reconstructed 3D image allows easy understanding of the hippocampal contour and demonstrates the structural relationship of the hippocampal formation to surrounding structures in vivo.
本研究旨在对活体犬海马结构进行三维(3D)解剖学阐释,并评估其与周围脑结构的关系。使用反转恢复分段3D梯度回波序列(即MP-RAGE:磁化准备快速梯度回波)在磁共振成像(MR)扫描仪上对三只正常的比格犬进行扫描。利用3D Slicer软件工具对MRI数据进行手动分割并重建为3D模型。从该3D模型评估海马结构与周围结构之间的空间关系。随着MPRAGE空间分辨率和对比度的提高,犬海马结构易于描绘。重建的3D图像便于理解海马轮廓,并展示了海马结构在体内与周围结构的结构关系。
