Table 1.
Mean and standard deviation of normalized perfusion measures relative to brain. Significance (P values) are the results of paired t‐tests between the initial value and first recheck, and first and second rechecks. Blood flow in the whole tumor declined significantly after the first recheck, and in the tumor center after the second recheck. Significant differences were not detected after adjusting for multiple comparisons
