Due to its excellent sensitivity, MR imaging is invaluable for the evaluation of lesions of the cord and spine. Several studies dedicated to diffusion-weighted MR evaluation of the cord and spine have been published. While diffusion-weighted MR imaging of the brain is routinely performed, it is seldom performed when imaging the spine due to serious limitations. While anatomical limitations may not be changed, the voxel size, phase-encoding direction, mode of k-space filling, and acceleration factor are all parameters that can be optimized in order to routinely obtain diffusion-weighted imaging of the spine on 1.5T and 3T scanners.
由于其出色的敏感性，磁共振成像在评估脊髓和脊柱病变方面具有极高价值。已有多项致力于脊髓和脊柱扩散加权磁共振评估的研究发表。虽然脑部扩散加权磁共振成像常规进行，但由于严重局限性，脊柱成像时很少进行。虽然解剖学限制可能无法改变，但体素大小、相位编码方向、k空间填充模式和加速因子都是可以优化的参数，以便在1.5T和3T扫描仪上常规获取脊柱的扩散加权成像。
