Landmark PositionDiaphragm level
Scan LocationAorta at diaphragm

Bolus Tracking Scan
Threshold Preset125 HU
Post Threshold Trigger(s) for Delay ScanArterial: Bolus Tracking Delay plus 20 seconds **(see tips)Portal Venous: 75 seconds
TipsScan must start 20 seconds AFTER reaching 125 threshold** Sequence usually triggers @ 15 sec plus 20 sec delay = 35 sec for Arterial Ph. Set Venous Phase @ 60 sec delay. ( 15 plus 60 sec delay = 75 sec Venous Phase.)
