Regional MRI Perfusion Measures Predict Motor/Executive Function in Patients with Clinically Isolated Syndrome
Figure 2
Correlation between performance accuracy and RT during the Complex Decision task and CBF/CBV values for CIS patients. Zero-order Pearson correlation coefficients between performance accuracy (a) and RT (b) during the Complex Decision task and CBF/CBV in 20 ROIs in the left (L) and right (R) hemispheres and the corpus callosum. Coefficients > 0.50 were significant at a Bonferroni-corrected alpha level of .0025 (indicated by horizontal solid lines). Asterisks indicate significant correlations which were also found to be condition specific (based on Fisher’s test for the difference between correlation coefficients in the “simple” and “executive” conditions).
