Calculate tract based weighted means
Extracting the weighted means of individual fiber pathways can be useful when you want to quantify the microstructure of an entire white matter structure. This is specifically useful for tract based...

A guide to quantifying head motion in DTI studies
It is unfortunately not common practice in diffusion imaging research to report on observed head motion of the participants in the scanner. Even though head motion can significantly influence study...

The diffusion tensor, and its relation to FA, MD, AD and RD
In DTI 101 we described how diffusion tensor imaging estimates brain microstructure by modeling diffusion of water in the brain. We briefly discuss that this is done by using ellipsoid or ball shaped...

DTI Quality Control - Part 4: Further reading
Analysis of diffusion images are complicated by the fact that errors can be easily hidden inside the calculated tensor data and not clearly show up in your final processed FA image. Quality control is...

DTI Quality Control - Part 2: Tensor fitting
After making sure your data was acquired correctly (see also this post) and all looked good - you can go ahead and start tensor fitting. At the core of tensor fitting is using the right gradient...

DTI Quality Control - Part 1: Acquisition
A major issue in DTI image analysis is quality control. Effective quality control for diffusion images relies both on pre tensor fitting (the diffusion weighted images; DWI), and post tensor fitting...
