To investigate the possibility of acquiring DTI data after intravenous administrations of contrast material GD-DTPA on patients with brain tumors, we acquired DTI data five times that were two DTI scans before (pre1, pre2), one DTI scan during (during3), and two DTI scans after (post4, post5) injections of the GD-DTPA agent on fourteen patients. There are significant differences between pre and during in ROIs of edema and tumor lesions for both Trace and FA and there are significant differences between during and post in ROIs of edema and tumor lesions for Trace, but not for FA.
