Stereotaxic white matter atlas based on diffusion tensor imaging in an ICBM template

Brain registration to a stereotaxic atlas is an effective way to report anatomic locations of interest and to perform anatomic quantification. However, existing stereotaxic atlases lack comprehensive coordinate information about white matter structures. In this paper, white matter-specific atlases in stereotaxic coordinates are introduced. As a reference template, the widely used ICBM-152 was u...

The effect of atlas selection on voxel based analyses of DTI data

Introduction: In recent years, voxel based analysis (VBA) studies have demonstrated the potential of diffusion tensor imaging (DTI) to detect white matter (WM) damage in patients with various neurological or psychiatric disorders. In VBA, all DTI data sets are transformed to an atlas or template, whereafter the diffusion measures of control subjects and patients are evaluated in each voxel. In ...

NODDI-DTI: Estimating Neurite Orientation and Dispersion Parameters from a Diffusion Tensor in Healthy White Matter

The NODDI-DTI signal model is a modification of the NODDI signal model that formally allows interpretation of standard single-shell DTI data in terms of biophysical parameters in healthy human white matter (WM). The NODDI-DTI signal model contains no CSF compartment, restricting application to voxels without CSF partial-volume contamination. This modification allowed derivation of analytical re...

Automatic Segmentation of White Matter Structures from DTI Using Tensor Invariants and Tensor Orientation

INTRODUCTION DTI analysis of brain structures has shown to be relevant in a number of neurological clinical pathologies, such as brain ischemia, multiple sclerosis or epilepsy, among others. In schizophrenia, group studies have demonstrated alterations in the diffusion of several fiber bundles within the white matter [1]. The automatic segmentation of these structures from DTI has spurred signi...
