Box-whisker plots of the ADC_44.5ms^mean and ADC_7.1ms^mean (a), ADC_44.5ms^5th and ADC_7.1ms^5th (b), and ADC_44.5ms^95th and ADC_7.1ms^95th (c) in peritumoral regions for primary central nervous system lymphomas (PCNSLs) and glioblastomas (GBMs). All three indices for ADC_7.1 ms were significantly higher than those for ADC_44.5 ms for both tumors (all p < 0.01, respectively) (a–c). No significant difference in any of the three indices of ADC_44.5 ms, ADC_7.1 ms, cADC, and rcADC was observed between PCNSLs and GBMs (a–i). Statistical tests used: ^*paired t-test, ^†unpaird-t test, ^‡Wilcoxon signed-rank test, ^§Mann–Whitney U test
