The CAT12 toolbox includes a module to assess what is called VBM data homogeneity. This post describes how to implement a much simpler but similar feature in Python.
Assessing quality on large neuroimaging datasets is a tedious task, especially combined with complex processing workflows, and as such is still an …

We have been trying different software packages for the preprocessing of diffusion-weighted imaging (DWI) and comparing their results in application to our cohort data, with a particular focus set on denoising. This post gives some brief feedback on our experience and details somewhat the reasoning that led to our final …

Processing neuroimaging data, regardless of the algorithm/software used, usually means generating more data, such as, among other possible types of outputs, numeric endpoints and, * more images *. Modern techniques now allow to use them over large collections of data, as seen with some recent large epidemiological studies and/or clinical …
