Contrast Medium Iv Injection - Siemens SOMATOM Emotion 6 Application Manual

General
Some of the Scan protocols, primarily for Angio exami-
nations, are already preset in the protocol with Auto load
in 3D. If you prefer not to use this preset, please de-
select the Auto load in 3D and save your scan protocol.
Some of the Scan protocols are preset in the protocol
with links to a postprocessing protocol. If you prefer
not to have this preset, 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 patient's weight and circulatory
system condition 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, as you may save contrast
medium on your routine studies since the Multislice
spiral scan can be up to 10 times faster than a 1 second,
single slice spiral scan.
For CTA studies (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.

of drugs and doses mentioned in this guide, please
