A, A 56-year-old man who was previously treated for a right occipital anaplastic astrocytoma, shows a progressive enhancing lesion in the medial aspect of the surgical resection cavity (inset) and PCT CBV map shows high CBV (CBV = 3.5 ml/100 g), suggesting recurrent/progressive tumor (arrows). B, Histopathology proven radiation/treatment necrosis (arrows) in a 34-year-old woman who underwent radiation and chemotherapy for a right fronto-parietal anaplastic astrocytoma shows low CBV (CBV = 1.1 ml/100 g) in a recurrent/progressive enhancing lesion (inset).
