In
this study, simulated diffusion-weighted signal in a model of white matter
was developed in order to study the relationship between diffusion time (tdif)
and ADC values. In vivo water diffusion experiments on the corpus callosum of
the rat brain were performed and compared to the simulated data. For in vivo
experiments and according to our simulated results, maximal and minimal ADC
values were found independent on tdif. Therefore in vivo measurements would
rather be acquired with a short tdif than with a larger one, resulting in a
higher Signal to Noise Ratio.
