|Scanner Used||Tomoscan SR-7000|
|Contrast Volume and Type||120ml of Ioxitalamate (Telebrix)-350|
|Area Scanned||Base of skull till C5-6|
|Length of Spiral (time)||40sec|
|Table Speed/Pitch||3mm/sec with a pitch of 1|
|3D Technique Used||Shaded-surface rendering technique|
- Patients had their heads tilted back and the gantry was angled so that it was perpendicular to the presumed course of the carotid arteries. The published results with shaded-surface rendering have been poor and this 3D technique should be avoided. MIP or volume rendering would be preferred.
- We find that there is no need to angle as the reconstruction can choose the optimal plane.
