Dear list,
I am performing single-voxel and multivoxel spectroscopy analysis and I need to
do partial volume correction. I found a thread on the list of someone asking if
it possible to achieve this using Freesurfer (see below), but there is no
answer saying how it is done. My question is how can I define the voxel (for
single-voxel) and the chosen voxels (for multivoxel) in the anatomical data set
to use the segmentation of only that defined voxel? I'm using a Siemens TrioTim
3T. All acquisitions are in the same session. The anatomical dataset is an
average of 2 MPRAGEs which I've already processed using FS, and the spectra
files are .rda. The header of the MRS data has info on vectors, but I don't
know how to use them.

Hi Pom,
yes, people here are using it for spectroscopy and for partial volume
correction (also for voxel placement).
cheers,
Bruce

Hi,
I am about to install FREE SURFER for my Spectroscopy work.
I want to use the software to perform GM/WM segmentation on my
single voxel data sets.
I am wondering if any one on this mailing list is currently
doing this task. I would like to get comments.
My study is on a GE 3T scanner.
thank you,
Pom"
Any advice, please?
Thank you!
Andreia
