CT Colonography

This is a minimally invasive procedure to detect colorectal polyps and cancers.
It is indicated for those who are unable or unwilling to undergo conventional colonoscopy.
No sedation is required.
Bowel preparation is necessary to avoid false results from faecal residue. Diet requirements together with a purgative will be explained to the patient at the time of booking. Carbon dioxide is pumped into the colon per rectum during the procedure. This is to distend the bowel somewhat. Abdominal discomfort is managed with an anti-spasmodic.
The investigation does expose you to radiation.
No intravenous contrast is used.
This procedure does not allow for biopsy or polypectomy.
