Contrast and Amount Used in Body CT for Pediatric Patients

Oral contrast is determined by weight as to the amount needed per patient:

1-7 Kg40-60 mL
8-11 Kg110-160 mL
12-15 Kg165-240 mL
16-42 Kg250-360 mL
Over 42 Kg480 mL +


Omnipaque 350 for Pediatric Patients.

6 ml (.02ml) of Omnipaque added to a 10 oz bottle of Apple Juice, kept in the Ped's radiology area. When mixed with juice it has a very good taste and patients will drink without a problem. To mix with any liquid, mix .02 ml of Omnipaque Contrast X the amount of liquid you are preparing. I.E. 500 ml Sterile Water for Irrigation, you would use .02 ml X 500 ml = 10 ml of Omnipaque Contrast.

Abdominal and pelvic CT contrast should be started at least 1 hours prior to the patient in the procedure area and may need to be longer but determined by the Radiologist. Just prior to the scan an additional amount approx. 30-45 mL should be given if patient tolerated. Sometimes water may be used as a contrast agent as well. On Infants, Omnipaque contrast can be added to their formula or breast milk and given via an infant bottle. Mix as above to mix with any liquid.

IV Contrast is used as well as oral contrast for patients having a CT Scan. Visapaque 320 is used in patients in Pediatric Body CT. The dose is based on the patients weight: 2 mL per Kg of Body Weight.
