Data were retrospectively analysed from 302 patients who underwent CT colonography (CTC) between August 2007 and August 2010 at Greenlane Hospital, the outpatient hospital for Auckland DHB. Twelve patients (4%) were found to have cancer, 24 (8%) had polyps >5 mm, and 111 (37%) had diverticular disease. 21 patients (7%) were referred for optical colonoscopy following their CTC, and 34 patients (11%) had follow-up recommendations resulting from extracolonic findings, including 24 recommendations for further imaging. The majority of the study population was New Zealand European (59%), Asian (17%), or Other Europeans (10%); only 5.1% were Māori and 4.1% Pacific Islander. The study authors recommend that Māori and Pacific Islanders be encouraged by primary health practitioners to present for bowel examination
