Eur Radiol
. 2009 Sep;
20(3):674-82.
PMID: 19760240
Objective: To assess the relationship between MRI-derived changes in whole-brain and ventricular volume with change in cognitive scores in Alzheimer's disease (AD), mild cognitive impairment (MCI) and control subjects. Material...

Eur Radiol
. 2009 Jul;
19(12):2826-33.
PMID: 19618189
We investigated progression of atrophy in vivo, in Alzheimer's disease (AD), and mild cognitive impairment (MCI). We included 64 patients with AD, 44 with MCI and 34 controls with serial...

Neuroimage
. 2008 Apr;
41(1):19-34.
PMID: 18378167
Tensor-based morphometry (TBM) creates three-dimensional maps of disease-related differences in brain structure, based on nonlinearly registering brain MRI scans to a common image template. Using two different TBM designs (averaging...

J Neurol
. 2008 Feb;
255(4):567-74.
PMID: 18274807
Background: Both cognitive tests and MRI-based measures have been suggested as outcomes in trials assessing disease-modifying therapies in Alzheimer's disease (AD). Objective: To compare changes in longitudinal MRI measures with...

Boyes R, Gunter J, Frost C, Janke A, Yeatman T, Hill D, et al.
Neuroimage
. 2007 Dec;
39(4):1752-62.
PMID: 18063391
Measures of structural brain change based on longitudinal MR imaging are increasingly important but can be degraded by intensity non-uniformity. This non-uniformity can be more pronounced at higher field strengths,...

Arch Neurol
. 2007 Jun;
64(6):849-54.
PMID: 17562933
Objective: To compare an automated intensity-based measure of medial temporal atrophy in Alzheimer disease (AD) with existing volumetric and visually based methods. Design: Longitudinal study comparing a medial temporal atrophy...

Neuroimage
. 2006 May;
32(1):159-69.
PMID: 16675272
We compared two methods of measuring cerebral atrophy in a cohort of 38 clinically probable Alzheimer's disease (AD) subjects and 22 age-matched normal controls, using metrics of zero atrophy, consistency,...

28(1):20-8.
PMID: 16406154
This study explores the diagnostic utility of atrophy rates of the cingulate gyrus, its subdivisions and the hippocampus in Alzheimer's disease (AD) and frontotemporal lobar degeneration (FTLD). Regions were manually...

Neuroimage
. 2004 Oct;
23(2):574-81.
PMID: 15488407
Manual segmentation of the hippocampus is the gold standard in volumetric hippocampal magnetic resonance imaging (MRI) analysis; however, this is difficult to achieve reproducibly. This study explores whether application of...
