It is recommended to use CARE Bolus in order to
achieve optimal contrast enhancement.
Both start delay time and injection rate are exam-/
patient-dependent. Whenever possible, I.V. injection
with a power injector is recommended for all scans .
Some guidelines to follow with respect to flow rate are
noted in the chart below.
Note: these injector guidelines are based on an antecu-
bital 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.For applications such as neonate or airway scanning,
the low tube output at 80 kV can be used to further
reduce the dose to the patient.
9.To further optimize MPR image quality we recom-
mend that you reduce one or more of the following
parameters: collimation, reconstruction increment
and slice width for image reconstruction.
Needle Size (gauge) Flow Rate (ml/sec.)
22 1.5
20 2.0 – 3.0
18 3.0 – 5.0
