Fig. 3B. —70-year-old man who had undergone partial resection of glioblastoma multiforme 4 months before permeability imaging. Permeability map generated from dynamic susceptibility contrast sequence, in which high permeability values are shown in red, reveals crescentic region of high permeability in left temporal lobe. This region corresponds to anterior portion of rim-enhancing mass seen in A. In this tumor, mean regional permeability value measured 0.064, and single area of maximum permeability value measured 0.072. Note that other red regions are seen that represent normal vessels rather than regions of elevated permeability.
