Influence of Signal Intensity Non-Uniformity on Brain Volumetry Using an Atlas-Based Method

摘要

ObjectiveMany studies have reported pre-processing effects for brain volumetry; however, no study has investigated whether non-parametric non-uniform intensity normalization (N3) correction processing results in reduced system dependency when using an atlas-based method. To address this shortcoming, the present study assessed whether N3 correction processing provides reduced system dependency in atlas-based volumetry.
