“…If needed, the tissue density images were further manually corrected for inaccurate skull-stripping and tissue probabilities were re-calculated. Based on the tissue density images, each individual’s cortical surface was extracted using a cortical reconstruction method using an implicit surface evolution (CRUISE) technique (33), which was shown to yield an accurate and topologically correct representation that lies at the geometric center of the cortical GM tissue (34). Each resulting cortical surface was represented as a triangle mesh comprising of approximately 300,000 mesh nodes.…”

Objective Cortical atrophy has been associated with late life depression (LLD) and recent findings suggest that reduced right hemisphere cortical thickness is associated with familial risk for major depressive disorder but cortical thickness abnormalities in LLD have not been explored. Further, cortical atrophy has been posited as a contributor to poor antidepressant treatment response in LLD but the impact of cortical thickness on psychotherapy response is unknown. This study was conducted to evaluate patterns of cortical thickness in LLD and in relation to psychotherapy treatment outcomes. Methods Participants included 22 individuals with LLD and 12 age matched comparison subjects. LLD participants completed 12 weeks of psychotherapy and treatment response was defined as a 50% reduction in depressive symptoms. All participants participated in Magnetic Resonance Imaging (MRI) of the brain and cortical mapping of grey matter tissue thickness was calculated. Results LLD individuals demonstrated thinner cortex than controls prominently in the right frontal, parietal, and temporal brain regions. Eleven participants (50%) exhibited positive psychotherapy response after 12 weeks of treatment. Psychotherapy non-responders demonstrated thinner cortex in bilateral posterior cingulate and parahippocampal cortices, left paracentral, precuneus, cuneus, and insular cortices, and the right medial orbito-frontal and lateral occipital cortices relative to treatment responders. Conclusions Our findings suggest more distributed right hemisphere cortical abnormalities in LLD than have been previously reported. Additionally, our findings suggest that reduced bilateral cortical thickness may be an important phenotypic marker of individuals at higher risk for poor response to psychotherapy.

“…Surface based methods typically construct a triangulated mesh based on either the WM boundary Fischl et al, 1999;Fischl and Dale, 2000;Shattuck and Leahy, 2002;Xu et al, 1999;Han et al, 2004), or the pial boundary (Davatzikos and Bryan, 1996), which is then deformed to find the opposing boundary.…”

“…Surface based cortical thickness methods try to ensure correct topology of the surface after initial segmentation of the WM boundary (Shattuck and Leahy, 2001;Xu et al, 1999;Han et al, 2004), using smoothness and self intersection constraints MacDonald et al, 2000), by correcting topological defects as they occur (Fischl et al, 2001;Segonne et al, 2005), or using a Laplacian function (Kim et al, 2005). Ensuring correct topology or surface regularity massively increases computational cost (Fischl et al, 2001;Han et al, 2004), may require a difficult balance of parameter weights (Kim et al, 2005;Scott et al, 2009), and reduces the model's ability to follow areas of high curvature such as extremely thin gyral stalks (Lohmann et al, 2003) or opposing sides of sulci with no clear CSF between, which can produce bias and error in thickness measurements (Scott et al, 2009).…”

A comparison of voxel and surface based cortical thickness estimation methods

Cortical thickness estimation performed in-vivo via magnetic resonance imaging is an important technique for the diagnosis and understanding of the progression of neurodegenerative diseases. Currently, two different computational paradigms exist, with methods generally classified as either surface or voxel-based. This paper provides a much needed comparison of the surface-based method FreeSurfer and two voxel-based methods using clinical data. We test the effects of computing regional statistics using two different atlases and demonstrate that this makes a significant difference to the cortical thickness results. We assess reproducibility, and show that FreeSurfer has a regional standard deviation of thickness difference on same day scans that is significantly lower than either a Laplacian or Registration based method and discuss the trade off between reproducibility and segmentation accuracy caused by bending energy constraints. We demonstrate that voxel-based methods can detect similar patterns of group-wise differences as well as FreeSurfer in typical applications such as producing group-wise maps of statistically significant thickness change, but that regional statistics can vary between methods. We use a Support Vector Machine to classify patients against controls and did not find statistically significantly different results with voxel based methods compared to FreeSurfer. Finally we assessed longitudinal performance and concluded that currently FreeSurfer provides the most plausible measure of change over time, with further work required for voxel based methods.

“…A battery of algorithms has been integrated in the proposed framework. These algorithms have been described and validated in detail in various publications [5,6,7,8]. We specifically aimed to test the hypothesis that there exists group differences in cortical atrophy patterns among PSP, MSA, and IPD.…”

Abstract.With the ability to study brain anatomy in vivo using magnetic resonance imaging, studies on regional brain atrophy suggest possible improvements for differential diagnosis of movement disorders with parkinsonian symptoms. In this study, we investigate effects of different parkinsonian syndromes on the cortical gray matter thickness and the geometric shape of the cerebral cortex. The study consists of a total of 24 patients with a diagnosis of probable progressive supranuclear palsy (PSP), multiple systems atrophy (MSA) or idiopathic Parkinson's disease (IPD). We examine dense estimates of cortical gray matter thickness, sulcal depth, and measures of the curvature in a surface-based cortical morphometry analysis framework. Group difference results indicate higher cortical atrophy rate in the frontal lobe in PSP patients when compared to either MSA or IPD. These findings are indicative of the potential use of routine MRI and cortical morphometry in performing differential diagnosis in PSP, MSA and IPD.
