DW-MRI and histological data for A-07 and R-18 melanoma xenografts showing that high ADC was associated with low cell density. Median ADC (A) and cell density (B) for A-07 and R-18 tumors, median ADC for A-07 tumors with low and high cell densities (cell densities below and above the median value of 1.8 × 105 cells/mm3) (C), and median ADC for R-18 tumors with low and high cell densities (cell densities below and above the median value of 4.2 × 105 cells/mm3) (D). Columns and bars represent mean values and standard errors [n = 10 (A and B), n = 5 (C and D)].
