Area ScannedTop to bottom of liver
Scan Delay12sec (approx)
Length of Spiral (time)30-35sec
Slice Thickness3mm
Table Speed/Pitch3-5mm/sec with a pitch of 1:1 to 1:7:1

Comment: A test bolus of 20ml is injected at 5ml/sec. A single scan is chosen just above the celiac axis. After an 8sec delay, 14 one-second scans are obtained with a one-second interscan delay. In these patients we prefer a dual-phase Spiral CT.
