Figure 2

Representative diffusion weighted images with voxel-based analysis. The images were cropped to show only the tumor region (51 × 45 voxels, 18.4 mm × 16.2 mm). (a) Diffusion weighted image with b = 0. (b) Diffusion weighted image with b = 750 s/mm2. (c–f) Results from mono-exponential analysis. (g–l) Results from bi-exponential analysis. The goodness of fit is shown in terms of RSS (e, k) and BIC (f, l). (m) Percent of AVV which have lower BIC for biexponential model fit than for monoexponential model fit. (n) Scatter plot of tumor volume and percentage of AVV. There was significant correlation between them (r = 0.55, p=0.02).
