B0-drift-induced global signal decrease in DWI data
causes a significant influence on the estimation of
diffusion parameters. Quantitative diffusion metrics (FA
and mean kurtosis) as well as directional information
(first eigenvectors in DTI) are affected by this
artifactual signal decrease during the scan session. By
interspersing the non-diffusion-weighted images
throughout the session, the signal decrease can be
estimated and compensated before processing, minimizing
the detrimental effects on all further analyses.
