Test Bolus
This is a low dose sequential protocol without table 
feed used to calculate the start delay of a spiral scan to 
ensure optimal enhancement after the contrast 
medium injection. The Dynamic Evaluation function 
may be used to generate the time density curve. 
You can find the “Test Bolus“ scan protocol in the chap-
ter “Specials“.
How to do it
1.Select the spiral mode that you want to perform, and 
then “Append” the Test Bolus mode under Special 
protocols.
2.Insert the Test Bolus mode above the spiral mode for 
contrast scan by “cut/paste” (with right mouse but-
ton).
3. Perform the Topogram, and define the slice position 
for Test Bolus.
4.Check the start delay, number of scans and cycle 
time before loading the mode.
5.A Test Bolus with 10 – 20 ml is then administered 
with the same flow rate as during the subsequent 
spiral scan. Start the contrast media injection and 
the scan at the same time.
