Time-by-medication-by-age interaction effects were identified in several association tracts of the left hemisphere and in the lateral aspect of the truncus of the corpus callosum in
voxel-based analysis due to a greater increase in FA in MPH-treated boys.
Quantitative evaluation of crossed cerebellar diaschisis, using
voxel-based analysis of Tc-99m ECD brain SPECT.
There are several methods based on the voxel-based morphometry or
voxel-based analysis that can be used to investigate WM impairments in schizophrenic patients.
Duncan, "Abnormal cerebral structure in juvenile myoclonic epilepsy demonstrated with
voxel-based analysis of MRI," Brain, vol.
Voxel-based analysis on PET/CT image was used in the apoptosis imaging visual analysis, which performs voxel-by-voxel subtraction of the change PET/CT before (pre-CK) and early after CK treatment (post-CK).
We opted to apply a
voxel-based analysis because it has been shown to be more sensitive to subtle WM differences than other approaches such as tract-based and ROI-based analysis [1].

Voxel-based analysis of diffusion tensor indices in the brain in patients with Parkinson's disease," European Journal of Radiology, vol.
Statistical parametric mapping (SPM; Wellcome Trust Centre for Neuroimaging), a
voxel-based analysis, can also be used by normalizing the individual scans to the same Montreal Neurological Institute (MNI) template spatially to calculate the ratio of specific to nonspecific binding.
The
Voxel-based analysis strategy (20,21) used in this study was the same as that used in previous DTI studies.
A
voxel-based analysis method was used to calculate alterations in GMV, and the tract-based spatial statistics method was used to calculate alterations in WM.
Gunter et al., "Improved DTI registration allows
voxel-based analysis that outperforms tract-based spatial statistics," NeuroImage, vol.
This is a fully automated whole-brain analysis technique that involves voxel-wise statistics on diffusion metrics but simultaneously minimizes the effects of misalignment by using the conventional
voxel-based analysis method.[sup][15],[16] Before image processing, all images were confirmed uncontaminated with major head motion.
