Table 4.
CBF values before and during radiotherapy (ml/100 g/min).
| High-perfusion area | Edema area | Normal gray matter | |||
|---|---|---|---|---|---|
| CBFmax | CBFmin | CBFmean | CBFmean | CBFmean | |
| Before radiotherapy | 77.17 ± 17.45 | 45.83 ± 9.47 | 66.09 ± 13.45 | 38.05 ± 7.81 | 40.44 ± 12.28 |
| During radiotherapy | 86.00 ± 35.79 | 50.67 ± 11.64 | 69.31 ± 16.96 | 40.23 ± 12.57 | 38.14 ± 12.60 |
| Test statistic | -0.647 | -1.336* | -0.314 | -0.492 | 1.077 |
| P values | 0.546 | 0.239 | 0.753 | 0.644 | 0.331 |
CBFmax/CBFmin/CBFmean represent the maximum, minimum, and average values of cerebral blood flow (CBF), respectively. The asterisk (*) represents the test statistic of Wilcoxon test and the others are t-test values.
