Influence of ffast value on the calculated ADC
| ffast | ADC1 (× 10−5 mm2/s) | ADC2 (× 10−5 mm2/s) |
|---|---|---|
| 0.75 | 66.42 | 88.76 |
| 0.7 | 61.19 | 81.15 |
| 0.65 | 56.31 | 74.29 |
| 0.6 | 51.76 | 68.07 |
| 0.55 | 47.50 | 62.39 |
| 0.5 | 43.51 | 57.20 |
| 0.45 | 39.75 | 52.43 |
| 0.4 | 36.21 | 48.03 |
| 0.35 | 32.87 | 43.95 |
| 0.3 | 29.72 | 40.17 |
| 0.25 | 26.73 | 36.64 |
| 0.2 | 23.89 | 33.35 |
| 0.15 | 21.20 | 30.27 |
Note.—Clinical ADCs (ADC1 and ADC2) were calculated on the basis of two b values: 0 and 1000 s/mm2. ADC1 was calculated on the basis of ADCslow and ADCfast in the normal WM of the patients. ADC2 was calculated on the basis of ADCslow and ADCfast in the ischemic parenchyma of the patients. When ffast is <0.55 both ADC1 and ADC2 are decreased.
