Hi:

  I need to get the complete visual tract. With DSI studio I got only the Optic Radiation (chiasma to occipital visual area). How can I do it? I have DWI images with 64 and 256 gradient directions. 2x2x2 mm voxels.

  Sincerely,


Gonzalo Rojas Costa

For most DWI data, tracking the optic nerve anterior to chiasma is not possible due to susceptibility artifacts. 

You may need to talk to your MR physicist to see if there are readout segmentation sequences available to handle this acquisition challenge.


Best regards,
Frank

Hi:

But, using Autotrack how can I get the complete visual tract? Not only the optic radiation?

Sincerely,

It is the CNII under the cranial nerve category.
