Diffusion-based Assay:Article Title: Alterations in white matter microstructural properties after lingual strength exercise in patients with dysphagia
Article Snippet: .. Data Preprocessing All diffusion data were processed using the “Pipeline for Analyzing braiN Diffusion images” (PANDA): a toolbox implemented in MATLAB (http://www.nitrc.org/projects/ panda/).9 This software employs several neuroimaging processing modules including the FMRIB Software Library (FSL), the Pipeline System for Octave and MATLAB (PSOM), the Diffusion Toolkit, the MRIcron to automatically perform a series of steps (i.e., skull removal, correction of eddy current distortion, build diffusion tensor models).9 Tract-Based Spatial Statistics (TBSS) were employed to evaluate voxel-based group differences for the values of fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), radial diffusivity (RD)9 and Local Diffusion Homogeneity (LDH).10 TBSS involves constructing a skeleton from the mean metric values of all aligned images following normalization, and subsequently projecting the obtained FA, MD, AD, RD, and LDH values from each participant onto this skeleton. .. Diffusion metrics for each participant were extracted for 20 tracts identified from the Johns Hopkins University (JHU)-ICBM-DTI-81 white matter atlas.9 Each global mean metric (FA, MD, AD, RD, and LDH) for each participant was obtained by averaging across the 20 tracts, and diffusion metric for each tract was divided by this global mean to account for any variability between participants, and the standardized metric was used in further statistical analysis.
