Figure 2. Tumor and normal tissue vascular permeability changes following brain irradiation.

Contrast uptake following brain irradiation. Increase in contrast uptake (Area Under the uptake Curve (AUC)) of normal appearing white matter (NAWM) and tumor following whole brain irradiation (WBRT). Data were normalized to the AUC at baseline, prior to beginning WBRT. Error bars represent the standard error of the means.
