Injection Rate3cc/sec
Contrast Volume and Type120cc of Omnipaque-350
Area ScannedFrom top of left hemidiaphragm through lower border of spleen (at least below celiac axis)
Scan Delay30sec / 60sec (of dual study)
Length of Spiral (time)Usually 20-30sec
Slice Thickness3mm
Table Speed/Pitch3-5mm/sec

3D Technique UsedVolume rendering for splenic aa and vein
Comment: This describes a dual-phase technique which also optimizes evaluation of the splenic aa and vein. Single-phase techniques can be used in most cases with the delayed-phase images usually easier to interpret.
