ACR's Guidelines For CT Colonography Interpretation Examined In Study At Digestive Disease Week

A study presented at Digestive Disease Week® 2008 examined the American College of Radiology's (ACR) CT colonography guidelines recommending that polyps ≤ 5mm in size not be reported on CT colonography by applying them to an endoscopic database that collected information about polyps that had been removed and processed. The guidelines also recommend that patients with one or two polyps 6 to 9 mm in size and no larger polyps can have repeat CT colonography in three years rather than prompt polypectomy. The database included information for 10,780 polyps removed from 5,079 patients (among 10,034 colonoscopies) over a five-year interval. Overall, the study determined that if CT colonography rather than colonoscopy had been used in this population, and assuming 100 percent sensitivity of CT colonography for polyps ≥ 6 mm and ACR interpretation recommendations, then 29 percent of all patients and 30 percent of patients over age 50 with high risk adenoma findings would have been interpreted as normal.
