Analysis of surface-based displacement vectors using spherical harmonic description (SPHARM) localizes shape changes accurately. However, it does not allow differentiating volume variations from shifting and/or bending. We propose a new approach to quantify local volume changes by computing the surface-based Jacobian determinant. This measurement is computed on the displacement vector fields estimated by a heat equation interpolation on the displacement vectors produced by SPHARM. Data… 

Vertex-Wise Shape Analysis of the Hippocampus: Disentangling Positional Differences from Volume Changes

This comprehensive analysis showed that in patients atrophy and positional changes co-occurred at the level of the posterior hippocampus, and this framework was validated on synthetic shapes, and a large database of healthy subjects and patients with temporal lobe epilepsy.

Hippocampal Shape Modeling Based on a Progressive Template Surface Deformation and its Verification

The experimental results showed that the proposed mesh-to-volume registration approach generated smooth surfaces with less volume differences and better shape similarity to input volumes than others, and it was sensitive in detecting subtle shape changes of hippocampus.

Surface-based morphometry reveals caudate subnuclear structural damage in patients with premotor Huntington disease

Caudate subnuclear atrophy measured using a surface-based morphometric technique is evident in pmHD, correlates with clinical variables, and may provide a more sensitive biomarker than global volumes.

Disentangling Hippocampal Shape Anomalies in Epilepsy

A surface-based framework is proposed to localize volume changes through measurement of Jacobian determinants, and quantify fine-scale position and curvature through a medial axis model of hippocampus shape anomalies in drug-resistant temporal lobe epilepsy and epileptic syndromes.

The study by Nguyen and colleagues demonstrates well the current limitations of MRI in focal epilepsy and highlights the need to continue efforts to move special imaging techniques out of the labs and into the clinical setting.

Gray matter structural compromise is equally distributed in left and right temporal lobe epilepsy

The results strongly support equivalent gray matter compromise in left and right TLE, and motivate the development of neuromarkers of outcome that consider both mesiotemporal and neocortical structures.

Patterns of subregional mesiotemporal disease progression in temporal lobe epilepsy

Objective: Evidence for disease progression in the mesiotemporal lobe is mainly derived from global volumetry of the hippocampus. In this study, we tracked progressive structural changes in the

Subregional Mesiotemporal Network Topology Is Altered in Temporal Lobe Epilepsy.

Preoperative network parameters, specifically the segregation of the ipsilateral hippocampus, predicted long-term seizure freedom after surgery and increased path length and clustering in patients, suggesting a shift toward a more regularized arrangement.

Imaging structural and functional brain networks in temporal lobe epilepsy

This review considers the application of advanced analytical methods in structural and functional connectivity analyses in temporal lobe epilepsy and highlights findings from graph-theoretical analysis that allow assessing the topological organization of brain networks.

Association of Optic Radiation Integrity with Cortical Thickness in Children with Anisometropic Amblyopia

The findings indicate that developmental changes occur simultaneously in the OR and visual cortex in amblyopia, and provide key information on complex damage of brain networks in anisometropic Amblyopia.



A Unified Statistical Approach to Deformation-Based Morphometry

We present a unified statistical framework for analyzing temporally varying brain morphology using the 3D displacement vector field from a nonlinear deformation required to register a subject's brain

Framework for the Statistical Shape Analysis of Brain Structures using SPHARM-PDM.

This manuscript presents a comprehensive set of tools for the computation of 3D structural statistical shape analysis, which has been applied in several studies on brain morphometry, but can potentially be employed in other 3D shape problems.

4D deformation modeling of cortical disease progression in Alzheimer's dementia

In order to continuously model changes associated with AD, deformation maps from 21 patients were averaged across a novel z‐score disease progression dimension based on Mini Mental State Examination (MMSE) scores and revealed significant perturbations in the deformation fields corresponding to the entorhinal cortex and hippocampus.

Boundary and Medial Shape Analysis of the Hippocampus in Schizophrenia

The results strongly suggest that the normalized hippocampal shape of the schizophrenic group is different from the control group, most significantly as a deformation difference in the tail region.

Voxel-Based Morphometry—The Methods

At its simplest, voxel-based morphometry (VBM) involves a voxel-wise comparison of the local concentration of gray matter between two groups of subjects. The procedure is relatively straightforward

Early DAT is distinguished from aging by high-dimensional mapping of the hippocampus

Assessments of hippocampal volume and shape derived from HDBM may be useful in distinguishing early DAT from healthy aging, and this work has suggested damage to the CA1 hippocampal subfield.

MRI-based high-dimensional hippocampal mapping in mesial temporal lobe epilepsy.

MRI-based evaluation of the hippocampus is important in the assessment and treatment of patients with mesial temporal lobe epilepsy (MTLE). Using MRI-based large-deformation high-dimensional mapping
