[Mristudio-users] transverse diffusion parameters

[Hangyi Jiang]

personally,  I think 0.1 is too low to get reliable (or consistent) fiber tracking results.

best,

Hi,

Any thoughts on how low one could go on FA threshold for tracking without introducing too much noise. I am using FA=0.2, and a lot of my patients have very severely atropic tracts and it is excluding a lot of the data. I can track more fibers if go as low as 0.1 but that makes me worry if I am introducing tracking error.

Also what has your experience been with transverse diffusion values, eigen value1 and 2 and 2DFA2-3 and 2DFA1-3. In my dataset they are more sensitive than FA or Trace.

Any thoughts, comments appreciated. Prachi
