Tractography

[Arian Klows]

Hi folks,

I am planning to run the tractography using DSI studio for a project.

I would really appreciate if you could answer my following questions.

1. I've the dicom data downloaded from neuroimaging site. 

I used step 1, open source images and loaded the dicom files.

Can I proceed with tractography? Like continue to step 2, 3 etc... 

Or should I worry about eddy current correction?

2. I found two options for reconstruction.  

            1. GQI and 2. QSDR

What's the ideal option for tractography approaches?

3. I was exploring this software and found  "enable tractography" option (very cool with a lot of tracts!!).

From which atlas "enable tractography" tracts have been loaded?

Also, for research/publication purpose, is it ideal to use that option  to run the tractography in multiple subjects?

Thanks,

A

You may need to check if the data have a lot of eddy current distortion: http://dsi-studio.labsolver.org/Manual/Parse-DICOM#TOC-Quality-Inspection

The choice depends on which analysis methods you choose: http://dsi-studio.labsolver.org/Manual/how-to-analyze-diffusion-data

GQI is for native space analysis, whereas QSDR is for MNI-space analysis.

 

3. I was exploring this software and found  "enable tractography" option (very cool with a lot of tracts!!).

Yes, http://dsi-studio.labsolver.org/Manual/automatic-fiber-tracking
