Diffusion imaging has been widely used in the brain, but its application in the spinal cord has been limited. Using line-scan diffusion imaging (LSDI), a technique that is less sensitive to magnetic susceptibility and motion artifacts than are other diffusion techniques, we have successfully imaged the spinal cord in children. The apparent diffusion coefficient and relative diffusion anisotropy of the normal spinal cord were measured. LSDI was compared with echo-planar diffusion imaging of the spine in three patients.
扩散成像已在脑部广泛应用，但在脊髓中的应用却受到限制。我们使用线扫描扩散成像（LSDI）——一种比其他扩散技术对磁化率和运动伪影不太敏感的技术——成功地对儿童脊髓进行了成像。测量了正常脊髓的表观扩散系数和相对扩散各向异性。并将LSDI与三名患者脊柱的回波平面扩散成像进行了比较。
