Contrast Medium
Test Bolus using CARE Bolus
You can use the CARE Bolus option as a Test Bolus.
Method
1.Insert a Bolus Tracking via the context menu prior to
the spiral.
2.Insert contrast from the context menu.
Note: By inserting contrast you are interrupting the
Auto range function preventing an automatic start
of the spiral.
3.Start with the topogram.
4.Position the premonitoring scan and the spiral.
5.Perform the premonitoring scan, position and
accept the ROI.
6.Start the monitoring scans and a small amount of
contrast medium (20 ml/2.5 ml/sec.). The rate of the
injection on the monitoring scans should match the
rate of injection used for the spiral scan.
Note: When you start the spiral manually, the sys-
tem switches to the Trigger tab card. The trigger line
is not shown at this stage.
7.Now you can read the proper delay from the Trigger
tab card.
8.Insert the delay in the Routine tab card and load the
spiral.
9.Start the spiral and injector at the same time with
the appropriate amount of contrast for the study
being performed.
