Outcome Measures
Primary Outcomes (1)
Which of four combinations of low residue diet, reduced laxative dose and oral contrast agent is best tolerated by patients and optimally prepares the colon prior ro CT colonography
Secondary Outcomes (1)
to compare the diagnostic performance of CT colonography after reduced bowel preparation and faecal tagging with conventional colonoscopy in patients undergoing both procedures

Eligibility Criteria
You may qualify if:
- Patients who are under investigation for suspected colonic neoplasia and over 50 years old:
- Symptomatic patients eg. change in bowel habit, rectal bleeding etc.
- Polyp surveillance
- Strong family history
- suspected neoplasia on previous investigation (e.g. barium enema)
You may not qualify if:
- patients under 50 patients undergoing surveillance for inflammatory bowel disease (due to poor diagnostic use of CT colonography in this specific patient cohort)
