We explored the possibility of using DTI as a longitudinal tool for probing fiber integrity in the rhesus monkey by evaluating reproducibility of fractional anisotropy (FA) measurement in the corpus callosum (CC) in a group of four young adult monkeys. Second, as part of a continuing effort to evaluate the potential of quantitative MRI to characterize aging in the primate brain, we made FA measurements in the CC of 47 monkeys aged 3-30 years.
