  1. *P value represents the comparison results of HGG and LGG using the t-test analyzation. †P value represents the comparison results of HGG and LGG using non-parametric Mann-Whitney U test. Values are presented as Mean ± standard deviations. ADC apparent diffusion coefficient, APT amide protein transfer, ADC mean mean value of ADC, ADC 20th 20th-percentile value of ADC, APT mean mean value of APT, APT 90th 90th-percentile value of APT, rCBF 90th 90th-percentile value or relative cerebral blood flow, rCBF mean mean value of cerebral blood flow
