6.Oral and rectal contrast administration: Depending
on the reason for the exam/status of the patient, oral
contrast may or may not be given to these patients.
In general, oral contrast is recommended to opacify
the intestinal tract, as unopacified bowel can have
the appearance of abdominal fluid or mass effect.
Oral, as well as rectal contrast may be required. Usu-
ally, a diluted mixture of iodine and water is used as
an oral agent. Different substances can be added to
this mixture to help reduce the bitter taste and make
it more pleasing to the child (apple juice and fruit
drink mixes are just a few of these). Barium may of
course be used in some cases as well. Negative con-
trast agents such as water are becoming more pop-
ular for delineation of stomach or bowel wall bor-
ders, or when 3D reconstructions are needed. The
user needs to be aware of all the contraindications of
any of the contrast agents they are using. Please
refer to the specific vendor’s recommendations.
7.I.V. contrast administration: In general, 1 – 2 ml per
kg of body weight should be applied, however, since
the scanning can be completed in just a few sec-
onds, please keep in mind that the total injection
time should not be longer than the sum of start
delay time and the scan time – do not inject contrast
after the scanning is finished.
