Hi Mahmoud,

Could you please give a little more detail on your statistical analysis?

E.g. In region-of-interest analysis it is possible to enter the SNR values as confounds.

And do you have a significant difference in SNR levels across sites?

Best wishes,

Barbara

Hi,

I wonder how one can consider the difference between SNR of DWIs acquired with almost the same parameters but at different sites? what is the method to cancel or normalize the effect of SNR difference on the DTI metrics?

Thank you,

Mahmoud
