General
Some of the Scan protocols, mainly for Angio exami-
nations, are already delivered with Auto load in 3D.
If you do not like, please deselect the Auto load in 3D
and save your scan protocol.
Some of the Scan protocols are delivered with links
to a postprocessing protocol. If you do not like our
suggestions, please delete the Range Parallel preset or
overwrite them with your own settings.
Contrast Medium IV Injection*The administration of a contrast medium depends on
the indication and on the delay times to be used during
the examination. The patients weight and circulatory
situation also play a role. In general, no more than 3 ml
per kg of body weight for adults and 2 ml per kg of body
weight for children should be applied.
As a rule of thumb, the contrast medium injection
should be stopped when the scan (or acquisition)
is finished. Keep this in mind, you may save contrast
medium in your routine study since the Multislice
spiral scan can be up to 32 times faster than a 1 second,
single slice spiral scan.
For CTA study (arterial phase), the principle is to keep
contrast injection for the whole scan. Thus, the total
amount of contrast medium needed should be calcu-
lated with the following formula:
CM = (start delay time + scan time) x flow rate.
CARE Bolus or Test Bolus may be used for optimal
contrast bolus timing. Please refer to the Application
Guide for special protocols.
