Bootstrap analysis of diffusion tensor and mean apparent propagator parameters derived from multiband diffusion MRI.

ABSTRACT:

Purpose

To directly compare diffusion metrics derived from multiband (MB) imaging sequences to those derived using a single-band acquisition.

Methods

In this work, diffusion metrics from DTI and mean apparent propagator MRI derived from a commercial MB sequence with an acceleration factor of 3 are compared with those derived from a conventional diffusion MRI sequence using a novel bootstrapping analysis scheme on oversampled diffusion MRI data. The average parameter values for fractional anisotropy and mean diffusivity derived from DTI, as well as propagator anisotropy and return to origin probability derived from mean apparent propagator MRI, are compared.

Results

Fractional anisotropy and propagator anisotropy are very similar when computed from data collected with
