Fig. 3.

Patient C was 50 years old with KPS = 90, PFS = 364 days, and OS = 546 days. Color overlays of CNI values on postcontrast T1-weighted images obtained at pre-, mid-, and post-RT scans are shown. The overlays were thresholded to show only regions with CNI >2. The selected volumes are highlighted in yellow. The spatial extent and magnitude of the regions with abnormal metabolism are much smaller than those for patient B, indicating much smaller metabolic lesions that further reduce with treatment. The patterns of changes in parameter values are seen in the bar graphs below.
