By means of modern 3D-visualization systems it is possible to render detailed reconstructions of very small morphological structures such as the inner ear. Aim of the present study was to demonstrate the imaging quality of a new 3D-segmentation program developed in the University of Hamburg. The investigation was carried out on a high-resolution MR-tomography of the author's labyrinth and facial nerve. The images were obtained with a fast-field-echo technique using a surface coil. 32 axial slices of 1.0 mm thickness were used for reconstruction. Thus it was possible to completely visualize cochlea, semicircular canals and facial nerve. Especially the filiform substructures of the inner ear could reliably be reconstructed. So the content of information of the MR-investigation could be increased by the 3D-technique applied.
借助现代三维可视化系统,可以对诸如内耳等非常小的形态结构进行详细重建。本研究的目的是展示汉堡大学开发的一种新的三维分割程序的成像质量。研究是在作者的内耳迷路和面神经的高分辨率磁共振断层扫描上进行的。图像通过使用表面线圈的快速场回波技术获得。使用32层厚度为1.0毫米的轴向切片进行重建。这样就可以完整地可视化耳蜗、半规管和面神经。尤其是内耳的丝状亚结构能够可靠地重建。因此,应用三维技术可以增加磁共振检查的信息量。
