Effect of geometric distortion correction on thickness and volume measurements of cortical parcellations in 3D T1w gradient echo sequences
Fig 2
Exemplary overlay of the cortical segmentations from the FreeSurfer parcellations of the distortion corrected (DC) (blue) and not distortion corrected (nDC) (red) images in axial, coronal, and sagittal view.
Purple areas indicate the overlap between the two parcellations.
