[Mristudio-users] Mean diffusivisy values in DTIstudio

[Susumu Mori]

Mean diffusivity is Trace/3, while the Trace = (lambda1 + lambda2 +
lambda3).

You can find "Trace" in DtiStudio.
So you should report this value as "Trace" or divide it by 3 and report it
as "mean diffusivity".

By the way, MD is called "Mean" because it is the mean of lambda 1-3.
