DTI has been used for mapping the structural network of human brain. The network is constructed by choosing various brain regions as nodes and fiber tracts connecting the regions as links. To investigate the effect of DTI SNR on the constructed network, a set of DTI data with different SNR was created from the 48 direction dataset. The result shows that SNR affects the accuracy of network while has less effect on the variation.
