The use of simultaneous
multiband radiofrequency (RF) pulses to accelerate volume coverage along the
slice direction is becoming increasingly popular. In this work, we attempt to
evaluate the impact on parameter calculations of parallel imaging in
combination with multiband excitation for DTI applications. The image quality
as well as the indexes was compared. This experiment shows that the accelerated
multiband sequence are highly reproducible in voxel-based analysis for
different parallel imaging factors, with no significant differences (p < 0.001).
In addition, the parallel imaging factor may have an influence on SNR and
distortion of the diffusion images.
