We investigated whether a rice pad could be used to reduce the geometric distortion in echo-planar diffusion-weighted images of the cervical spinal cord. In 10 healthy volunteers, we obtained sagittal plane images using the same imaging parameters with and without a rice pad. Two reviewers classified geometric distortion and visually assessed images. Use of a rice pad significantly reduced geometric distortion in the cervical spinal cord.
我们研究了使用稻垫是否可以减少颈椎脊髓的磁共振扩散加权成像中的几何变形。在 10 名健康志愿者中，我们使用相同的成像参数分别进行了带有和不带有稻垫的矢状面图像采集。两名评审员对几何变形进行分类并对图像进行了评估。使用稻垫可显著减少颈椎脊髓的几何变形。
