Journal ArticleDOI
Multi-Atlas Segmentation with Joint Label Fusion
TL;DR: A new solution for the label fusion problem in which weighted voting is formulated in terms of minimizing the total expectation of labeling error and in which pairwise dependency between atlases is explicitly modeled as the joint probability of two atlas making a segmentation error at a voxel is proposed.
Journal ArticleDOI
Large-scale evaluation of ANTs and FreeSurfer cortical thickness measurements.

TL;DR: The largest evaluation of automated cortical thickness measures in publicly available data is conducted, comparing FreeSurfer and ANTs measures computed on 1205 images from four open data sets, with parcellation based on the recently proposed Desikan-Killiany-Tourville cortical labeling protocol.
Journal ArticleDOI
Automated Volumetry and Regional Thickness Analysis of Hippocampal Subfields and Medial Temporal Cortical Structures in Mild Cognitive Impairment

TL;DR: Thickness analysis results are consistent with volumetry, but provide additional regional specificity and suggest nonuniformity in the effects of aMCI on hippocampal subfields and MTL cortical subregions.
Journal ArticleDOI
Nearly Automatic Segmentation of Hippocampal Subfields in In Vivo Focal T2-Weighted MRI
Paul A. Yushkevich,Hongzhi Wang,John Pluta,Sandhitsu R. Das,Caryne Craige,Brian B. Avants,Michael W. Weiner,Susanne G. Mueller +7 more
TL;DR: The results support the feasibility of subfield-specific hippocampal morphometry in clinical studies of memory and neurodegenerative disease.
Journal ArticleDOI
Registration based cortical thickness measurement
TL;DR: A diffeomorphic registration based cortical thickness (DiReCT) measure is introduced where a continuous one-to-one correspondence between the gray matter-white matter interface and the estimatedgray matter-cerebrospinal fluid interface is given by a diffeomorph mapping in the image space.
