FIG 4. Temporal variations of the DT MR imaging and proton MR spectroscopy indices of the patient groups. Error bars represent the SDs of values.
A, NAA/Cr ratio. A reduction of average of NAA/Cr ratios of the patient group 2 is shown (P = .04).
B, Mean isotropic ADC value. An increase in average of mean isotropic ADC values of the patient group 2 is observed (P = .0085).
C, Mean FA value. A decrease in average of mean FA values of the patient group 2 is shown (P = .004).
