Artifacts that can distort the appearance of the cervical spinal cord are caused by data truncation during MR image reconstruction. We used a phantom and then correlated anatomic sections with MR images in cadavers and normal volunteers to evaluate the effect of truncation artifacts on the MR appearance of the spinal cord. When truncation artifacts are minimized, the gray matter and major white-matter columns in the cervical cord can be recognized. T2-weighted gradient-echo MR techniques can best differentiate gray from white matter.
在磁共振成像（MR）图像重建过程中的数据截断会导致一些伪影，这些伪影会扭曲颈脊髓的外观。我们使用了一个模型，然后将尸体和正常志愿者的解剖切片与MR图像进行对比，以评估截断伪影对脊髓MR表现的影响。当截断伪影减到最小时，颈髓中的灰质和主要白质柱可以被识别出来。T2加权梯度回波MR技术能够最好地区分灰质和白质。
