FIG 1. A, BOLD fMR activation from a finger-tapping paradigm coregistered to an axial T1-weighted image (500/14 [TR/TE]) in patient 9. Pathologic analysis revealed a right parietal lobe glioblastoma multiforme. The areas in yellow correspond to an R value of 0.65. The areas in red correspond to an R value of 0.50. There is robust activation in the left motor cortex. The activation in the right motor cortex is barely perceptible (arrows).
B, A graph of the volume of activation for different R values for patient 9. For all R values that reveal activation, the volume of activation is greater on the side opposite the tumor.
