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

Figure 8

Fitted parameters of the second part of the histogram for the different age classes: amplitudes (-) and (- -) of the exponential decay curves (a), the diffusion constants and of the exponential decays (b), the amplitude of the Gaussian curve for the CSF component (-) and the value of the straight line at the position 0.875 10⁻³ mm²/s (- -) (c), the peak position μ₆ (d) and the width (FWHM) (e) of the Gaussian curve for the CSF component. In all cases, the parameters are shown for all selected patients (bold line) and for the results of the three subsets of patients.
