Extrapolation-Based References Improve Motion and Eddy-Current Correction of High B-Value DWI Data: Application in Parkinson’s Disease Dementia
Table 1
Accuracy of motion and eddy-current correction methods.
The table shows mean (standard deviation) of rotation, translation, scale and skew parameters obtained by registering FA-volumes calculated using high b-values to those calculated using low b-values. Top two sub tables show results from conventional motion and eddy-current correction (C-MEC) using FSL and ElastiX whereas the bottom two subpanels show results from CSF-corrected and CHARMED-based extrapolation-based motion and eddy-current correction (EB-MEC).
