Impact of fixation, coil, and number of excitations on diffusion tensor imaging of rat brains at 7.0 T
The authors of this study set out to compare diffusion tensor imaging (DTI) parameters in vivo and ex vivo in the brain and to explore the effects of radiofrequency coil and number of excitations on ex vivo DTI parameters. By obtaining DTI maps from rat brains and comparing ex vivo signal-to-noise ratio with different coils and number of excitations, it was possible to conclude that the impact of fixation, coil, and number of excitations on DTI parameters should be taken into consideration in clinical and experimental studies.
