Scanner Used

GE HiSpeed Advantage

Injection Rate

Contrast Volume and Type

None

Area Scanned

Depends on clinical question (i.e. bronchi vs airway)

Scan Delay

None

Length of Spiral (time)

Up to 30sec

3D Technique Used

Shaded surface

Comment: This technique will have a limited scan distance of 9cm. We believe you can increase the pitch to 2 which gives you 18cm coverage, which is enough for the trachea and major airways. Newer single detector scanners can cover a larger volume and the enrite airway scanned.
