Correlations between cortical changes in MRI parameters 6 days after UUO surgery. Correlation coefficient r is shown with respective p value. Note that p value in dark red is not significant (p ≥ 0.05). In the r and p plots, 1-PSR, 2-R1, 3-R2, 4-ADC, 5-NOE (-3.5 ppm), 6-NOE (-1.6 ppm), 7-DS (0.0 ppm), 8-CEST (1.2 ppm), 9-CEST (2.2 ppm), 10-CEST (3.5 ppm).
