<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I am interested in studying DTI changes (MD, I am wondering whether it will appropriate to study axial diffusivity also in the sense for instance FA is more for WM than GM) in gray matter between control and our patient population. I am wondering what is way to segment white matter (WM) from gray matter (GM).</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> I am also interested in extracting different lobes of the brain to study GM changes in each lobe. Basically based on our VBM results where I see GM volume changes I would like to study whether DTI measure MD changes in frontal, temporal, occipital and parietal lobes. If so, is there a way I can use the atlases to separate out different lobes of the brain.</FONT></DIV>
