Table 2. Susceptibility Values for Collecting Veins and Other Brain Areas.
| Susceptibility | DVA with T2 Hyperintensity (Group E+; n = 9) | DVA without T2 Hyperintensity (Group E-; n = 18) | P |
|---|---|---|---|
| χvein (ppb) | 196.5 ± 27.9 | 167.7 ± 33.6 | 0.036 |
| χbackground (ppb) | -5.6 ± 12.0 | 4.1 ± 15.9 | 0.122 |
| Normalized χvein (ppb) | 202.0 ± 32.6 | 163.6 ± 32.3 | 0.007 |
| χcontrol (ppb) | -7.8 ± 27.7 | -14.8 ± 11.2 | 0.459 |
χvein = susceptibility of draining veins, χbackground = susceptibility of adjacent brain tissue, χcontrol = susceptibility value of control brain parenchyma
