Comparison (P < .05) of the image quality of unpaired cerebral sinuses and veins in TOF MRV, CE MRV, and MPRAGE sequences
| Venous structure | Mean scores | CE/TOF | CE/MPRAGE | MPRAGE/TOF |
|---|---|---|---|---|
| CE/TOF/MPRAGE | Superior | Superior | Superior | |
| Superior sagittal sinus | 3.0/2.9/2.0 | None | CE | TOF |
| Inferior sagittal sinus | 2.3/1.6/2.0 | CE | CE | None |
| Vein of Galen | 3.0/2.6/3.0 | CE | None | MPRAGE |
| Straight sinus | 3.0/3.0/2.7 | None | CE | TOF |
| Intercavernous sinus | 2.6/0.4/2.1 | CE | CE | MPRAGE |
| Basilar plexus | 0/0/0 | None | None | None |
Note:—CE indicates contrast-enhanced MR venography; TOF, time-of-flight MR venography; MPRAGE, magnetization-prepared rapid acquisition of gradient echo.
