The arithmetic mean plus/minus standard deviation and values demonstrating the significance of pre- to postinterventional changes are listed. Spearman rank correlation coefficients (rho) and corresponding values demonstrating the significance of correlations in changes across all 10 patients at each ROI are also listed. values are calculated based on changes at each specific ROI and do not compare differing ROIs to one another. Significant values are marked with an asterisk.
