In all cases, the treating physician should be consulted prior to the examination, as CT scans should only be performed with a medical referral due to radiation exposure.
Patients receive about 1.5 litres of fluid one hour before the scan, into which 2 dl of high osmolarity fluid is added in order to fill the small intestine with fluid, a negative contrast agent, which allows a more accurate assessment of the small intestine. Our colleague will inform you about the schedule of this, please follow it exactly in all cases! Large amounts of fluid ingested may later cause harmless diarrhoea.
If your doctor orders an examination with contrast agent, you will also need kidney function laboratory results that show creatinine and urea levels. In the case of a scan with contrast agent, you should not eat for 6 hours beforehand.
