CBVmax obtained using methods 1 and 2
| Method | All Tumors, Mean (range) | AC (n = 21), Mean (range) | OA (n = 8), Mean (range) | OD (n = 5), Mean (range) |
|---|---|---|---|---|
| Method 1 | 4.01 (1.54–6.99) | 3.30 (1.54–6.65) | 5.33 (3.07–6.65) | 5.04 (2.74–6.99) |
| Method 2 | 1.63 (0.70–3.51)* | 1.44 (0.70–2.46) | 1.53 (1.26–1.94) | 2.21 (1.47–3.51) |
Note:—AC indicates astrocytoma; OA, oligoastrocytoma; OD, oligodendroglioma; rCBV max, maximum relative cerebral blood volume.
* P < .001 for method 1 versus method 2 by Wilcoxon test.
