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. Usually, a
diluted mixture of iodine and water is used as an oral
agent. Different substances can be added to this mix-
ture to help reduce the bitter taste and make it more
pleasing to the child (apple juice, fruit drink mixes are
just a few of these). Barium may of course be used in
some cases as well. Negative contrast agents such as
water are becoming more popular for delineation of
stomach or bowel wall borders, or when 3D recon-
structions 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 rec-
ommendations.
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 seconds,
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.
