TABLE 3:
Comparison of relative cerebral blood volume and vascular permeability measurements in patients with primitive neuroectodermal tumors with low grade gliomas (grade II/IV) and high grade gliomas (grade III/IV and IV/V)
| Tumor Type | rCBV | SD | Ktrans | SD |
|---|---|---|---|---|
| PNET (n = 12) | 4.76 | 1.99 | 0.0033 | 0.0035 |
| Low grade glioma (n = 30) | 2.14 | 1.67 | 0.0005 | 0.001 |
| P value | <.0005 | <.05 | ||
| High grade glioma (n = 55) | 5.82 | 3.57 | 0.0016 | 0.003 |
| P value | 0.53 | 0.19 |
Note.—rCBV indicates relative cerebral blood volume; Ktrans, vascular permeability (s−1); PNET, primitive neuroectodermal tumor.
