Brain image segmentation followed by region-of-interest
(ROI)-based analyses is a way to quantify subtle
variations of MR image intensity. In this contribution
we present an approach to improve the automated
segmentation of deep gray matter with FIRST that relies
on the incorporation of prior anatomical information
from secondary image contrasts with high-contrast in the
critical brain regions. The proposed technique is solely
pre-processing-based and, thus, does not require
modification of the actual segmentation algorithm.
