Voxel-guided morphometry ("VGM") and application to stroke.

Voxel-guided morphometry ("VGM") and application to stroke.

Monitoring of cerebral diseases associated with a change of morphology (e.g., stroke) requires unprecedented accuracy for quantification of its morphological progression for each voxel. The purpose of this paper is to provide a technique [voxel-guided morphometry (VGM)] to quantify macroscopic anato...
