We evaluated our proposed T2wsup-DWI method of reducing CSF-partial volume effects (PVE) on DTI. We assessed the errors in ADC and FA and the comparison of the ADC SNRs with several methods with simulation, and brain study. We clarified that our proposed T2wsup-DWI technique was superior to already proposed water suppression DWI methods of FLAIR and non-b-zero (NZE) methods in both of the ADC-SNR and the reduction effects of CSF-PVE in DTI parameters of ADC, FA, and tractograpy, typically at the portion of the fornix crus or genu of the corpus callosum which are close to the ventricle.
