Dear All:
I'm wondering if any one has tools for assessing the signal/noise ratio of
DTI raw images.
A recent publication " Diffusion tensor imaging at low SNR: nonmonotonic
behaviors of tensor contrasts. Landman et al. Magnetic Resonance Imaging 26
(2008) 790800" reported that the FA value was affected by signal/noise
ratio. So, if I want to compare the FA between patients and control
subjects, I need to assess if the signal/noise ratio of two groups were
match.
Any help is appreciated.
Best
