Contrast Medium

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 syngo Dynamic Evaluation 
function may be used to generate the time density 
curve. You will find the Test Bolus scan protocol in the 
chapter Specials.

Method

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 contrast spiral 

scan of interest using cut/paste (with right mouse 
button).

3.Perform the topogram and define the slice position 

for the 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.
