Table 2.
rCBF and measured values of parameters by NIRS/ICG.
| Ratio | Control (a) (N = 12) | Normal rCBF (b) (N = 22) | Reduced rCBF (c) (N = 7) | P value | |
|---|---|---|---|---|---|
| a versus b | b versus c | ||||
| ΔICG max | 1.08 ± 0.18 | 1.01 ± 0.15 | 0.92 ± 0.14 | 0.1109 | |
| TTP | 0.97 ± 0.08 | 1.03 ± 0.16 | 1.23 ± 0.16 | 0.5205 | 0.0093* |
| RT | 1.00 ± 0.09 | 1.05 ± 0.12 | 1.24 ± 0.14 | 0.4826 | 0.0034* |
| BFI | 1.09 ± 0.21 | 0.97 ± 0.15 | 0.75 ± 0.15 | 0.1455 | 0.0213* |
Ratio is given as affected side to non-affected side ratio.
Values are given as mean ± standard deviation. *A P value < 0.05 was defined as statistically significant.
BFI, blood flow index; ICG, indocyanine green; NIRS, near-infrared spectroscopy; rCBF, regional cerebral blood flow; RT, rise time; TTP, time to peak.
