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. I.V. injection with a power injector
is recommended for all scans whenever possible.
Some guidelines to follow with respect to flow rate are
noted in the chart below.
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.
