Fig. 3.

Pretreatment (top row) and post-treatment (bottom row) 3D volume renderings of each parameter’s assessment of the tumor extent of a representative patient (different from that displayed in Fig. 2) are presented. Each volume is rendered at 50% of each respective parameter’s maximum value obtained from the pretreatment study (i.e., only those voxels with values >50% of the maximum pretreatment value are displayed). Comparing the top row to the bottom row, the T₁, K^trans and ν_e maps indicated a tremendous drop in the extent of disease, while the τ_i map presents some residual areas of elevated τ_i. It is important to note that the T₁, K^trans and ν_e maps still have voxel values that are elevated above healthy values, but they are no longer above 50% of the maximum value obtained from the pretreatment study. Post-treatment ADC rendering shows an increase in overall ADC when compared to pretreatment rendering.
