| Lateral Tentorial Sinus Branch* | Right Lobe | Left Lobe |
|---|---|---|
| ATBV and ATV trunk | 30 | 29 |
| MTBV | 25 | 26 |
| PTV | 27 | 27 |
| MTV | 28 | 26 |
| VL termination | 47 | 47 |
| LTS | 23 | 30 |
| Transverse sinus | 12 | 10 |
| Indeterminate | 12 | 7 |
| Not visualized | 8 | 8 |
Note.—ATBV indicates anterior temporobasal vein; ATV, anterior temporal vein; MTBV, middle temporobasal vein; PTV, posterior temporal vein; MTV, middle temporal vein; VL, vein of Labbé; LTS, lateral tentorial sinus.
* Posterior temporobasal vein and occipitobasal vein not included in assessment because of poor visibility.
