A deformation‐based morphometry study of patients with early‐stage Parkinson’s disease
European Journal of Neurology, 2010Background and purpose: Previous volumetric magnetic resonance imaging (MRI) studies of Parkinson’s disease (PD) utilized primarily voxel‐based morphometry (VBM), and investigated mostly patients with moderate‐ to late‐stage disease. We now use deformation‐based morphometry (DBM), a method purported to be more sensitive than VBM, to test for atrophy ...

Quantifying cerebral changes in adolescence with MRI and deformation based morphometry
Journal of Magnetic Resonance Imaging, 2008AbstractPurposeTo identify and quantify structural changes in the maturing brain between childhood and adolescence.Materials and MethodsTwo three‐dimensional T1‐weighted MR volumes of the brain were acquired from eight subjects, 6 to 7 years apart. The subjects were 9 to 12 years old on the first scan and 15 to 19 years old on the second scan.

Blacks are at higher risk of developing cognitive impairment with age than non-Hispanic Whites, yet most brain morphometry and cognition research is performed with White samples or with mixed samples that control for race or compare across racial groups.

Deformation-based nonlinear dimension reduction: Applications to nuclear morphometry
2008 5th IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2008We describe a new approach for elucidating the nonlinear degrees of freedom in a distribution of shapes depicted in digital images. By combining a deformation-based method for measuring distances between two shape configurations together with multidimensional scaling, a method for determining the number of degrees of freedom in a shape distribution is ...

Visualizing Braak stages with deformation‐based morphometry in super‐sampled MRI
Alzheimer's & Dementia, 2023AbstractBackgroundUnlike MRI data, histological data collected post‐mortem can’t be used to study the longitudinal formation of neurofibrillary tangles (NFT) and corresponding brain changes over time for individuals. Although structural MRI offers the possibility of non‐invasive longitudinal antemortem imaging, its resolution is a limiting factor ...

Anatomic Differences in Early Blindness: A Deformation‐Based Morphometry MRI Study
Journal of Neuroimaging, 2012ABSTRACTBACKGROUND AND PURPOSEThis study aims to investigate the regional changes in the early onset of blindness using the deformation‐based morphometry (DBM) method.METHODSA total of 15 early blindness and 30 gender‐ and age‐matched sighted control subjects were recruited for the study.
