Note: these injector guidelines are based on an
antecubital injection site. These guidelines may need
to be adjusted if the site is more peripheral.

Central lines and ports may need to be hand injected
or power injected at a very low flow rate (1 ml/sec.).
PIC lines and 24 gauge (or smaller) lines are usually
hand injected. All of these protocols should be decided
on by your institution's appropriate personnel.
8. 80 kV was also used for applications when the
lowest achievable mAs at 110 kV was still higher than
necessary for sufficient noise level (for technical
reasons, generators need to operate at a certain mini-
mum current for stable operation). For applications
such as neonate or airway scanning, the low tube out-
put at 80 kV can be used to further reduce the dose to
the patient.
9. Please observe the recommended mAs settings in
the chronicle.
Note, that these recommendations are valid for the
default tube voltage of the specific protocol.
10. To further optimize MPR image quality we
recommend that you reduce one or more of the follow-
ing: collimation, reconstruction increment, pitch
factor while using a wider slice width for image recon-
struction.
