Abstract

We evaluated the effectiveness of distortion correction using a nonrigid image registration method in diffusion-weighted imaging, comparing it with readout-segmented echo planar imaging (RS-EPI). Unlike the RS-EPI, the effectiveness of the distortion correction of the nonrigid registration method depended on the slice level, being most accurate at the level of the basal ganglia, lateral ventricle, and centrum semiovale.

摘要

我们评估了使用非刚性图像配准方法在扩散加权成像中进行失真校正的效果，并将其与读出分段回波平面成像（RS-EPI）进行了比较。与 RS-EPI 不同，非刚性配准方法的失真校正效果取决于层面，在基底节、侧脑室和半卵圆中心层面最为准确。
