The spinal cord is an important part of the nervous system and provides the connection of the brain with the periphery. It consists not only of a large number of longitudinal fibers, but also contains collateral fibers and a central gray matter structure, which are part of autonomous circuits. Magnetic resonance diffusion tensor imaging can reveal this complex fiber architecture in great detail. This report summarizes the normal findings for ADC, diffusion anisotropy, and diffusion eigenvector directions in the spinal cord. Sagittal and axial diffusion-weighted images of the spinal cord were obtained with line scan diffusion imaging (LSDI) in adults, children, infants, and a spinal cord specimen.
脊髓是神经系统的重要组成部分，它提供了大脑与外周之间的联系。它不仅由大量纵向纤维组成，还包含侧支纤维和中央灰质结构，这些都是自主神经回路的一部分。磁共振扩散张量成像可以非常详细地揭示这种复杂的纤维结构。本报告总结了脊髓中表观扩散系数（ADC）、扩散各向异性和扩散特征向量方向的正常表现。通过线扫描扩散成像（LSDI）获得了成人、儿童、婴儿以及一个脊髓标本的脊髓矢状位和轴位扩散加权图像。
