Dear FSL users,
I have a 64 Direction DTI dataset where diffusion was only sampled on the half sphere instead of the whole sphere. I noticed my tractography results showed very low connectivity between my language ROIs (pars opercularis and posterior superior temporal gyrus). I'm presuming it's due to the half sphere scheme. Do half sphere and whole sphere DTI schemes change the results substantially?
I would like to acquire diffusion on the whole sphere in the future. Do you know what parameter/setting on a Siemens Verio 3T would need to be changed to allow for that?
Thanks,
SH
