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 enhancing regions for primary central nervous system lymphomas (PCNSLs) and glioblastomas (GBMs). For each tumor, each index for ADC_7.1 ms was significantly higher than the corresponding index for ADC_44.5 ms (each p < 0.01, respectively) (a-c). Comparisons of the cADC^mean (d), cADC^5th ©, and cADC^95th (f) between PCNSLs and GBMs. Each index for the cADC was significantly higher in PCNSLs than in GBMs (each p < 0.01, respectively). Comparisons of the rcADC^mean (g), rcADC^5th (h), and rcADC^95th (i) for PCNSLs and GBMs. Each index for the rcADC was significantly higher in PCNSLs than in GBMs (each p < 0.01, respectively). Statistical tests used: ^*paired t-test, ^†unpaird-t test, ^‡Wilcoxon signed-rank test, ^§Mann–Whitney U test
