[Mristudio-users] ROI placement

[Demitry Kazlouski]

Hello,

 

Can someone suggest me a better way to place ROI(s) within a white matter
tract and get accurate FAs (fractional anisotropy values) for a group
comparison?

I see two ways by using ROI tab. One is to place ROI of a fixed shape for
all subjects. The other way is to create manually drawn ROIs. If I use the
first method, there would be some uncertainty because the fibers of other
white matter tracts might be selected. If I use the second method, my ROIs
would have different areas and, I assume, this would affect FA values. It
seems like both methods have pros and cons. Please let me know your opinion.
Thanks.
