Parameterization of the Age-Dependent Whole Brain Apparent Diffusion Coefficient Histogram

Figure 2

Histogram of ADC values from all patients. The position of the peak is marked by a black line; the position of the ADC values where the FWHM is reached is marked by red lines (ADC_50%_below and ADC_50%_above). The histogram was split into a first part (lower values than ADC_50%_above, blue) and a second part (larger values than ADC_50%_above, green). The value of ADC_50%_above lies between two data points; therefore the part of the histogram between the highest data point of the first point and the lowest part of the second point is shown in black.
