I have noticed that most of my diffusion scans unfortunately have a chemical shift artefact. Here’s an example of such artifact:
The artefact is also quite obvious in the ODF map:
Once I generated streamlines for the whole brain, the artefact wasn’t as obvious, but I’m sure it still affected the tracking process. Here’s what it looks like:
My question is, is there any way I can work around this artefact using MRtrix? I’m trying to track the optic radiations, which will obviously be affected by the artefact, but how badly will it do so? I know my question is quite vague, but I’m honestly just looking for suggestions on how to handle this data. Is the data even salvageable?
As always, thanks for the help.
