Extrapolation-Based References Improve Motion and Eddy-Current Correction of High B-Value DWI Data: Application in Parkinson’s Disease Dementia
Table 2
Effect of motion and eddy-current correction method on group comparison.
Results are presented as mean (standard deviation), and were for the left pair of columns obtained using conventional motion and eddy-current correction (C-MEC) whereas the right pair of columns show values obtained using extrapolation-based motion and eddy-current correction. Significant differences were observed more frequently between the healthy controls and PDD patients when using the extrapolation-based correction. Results were similar but not identical when each hemisphere was compared separately.
