Results indicate the percent of pixels within each image that were assigned to a given class. For each case, samples for which stereostactic information was available are marked by their position in parenthesis using alpha and alphanumeric labeling systems. Italicized results are in apparent disagreement with diagnosis and further discussed in the text. A, astrocytoma; GL, glioma; Med, medium; MG, meningioma; OA, oligoastrocytoma; O, oligodendroglioma.
