Screening performance on adenoma and advanced neoplasia detection is consistent among radiologists using metrics that included advanced neoplasia detection rate and per-polyp endoscopic confirmation rate.
Before Medicare halted coverage for screening CT colonography in March 2009, the technique was indeed being used appropriately, a study has found.
High-quality CT colonoscopy diagnostic images can be maintained while reducing the radiation dose, according to a new study.
A new modeling study has found that people who undergo colonoscopy at age 50 years in which no precancerous polyps are found can be rescreened at age 60 years with one of three alternative methods, rather than undergoing colonoscopy every 10 years.
It may be reasonable to use methods other than colonoscopy to rescreen people who had negative results on their first screening colonoscopy.
CT colonography can accurately detect adenomas 10 mm or larger in patients who did not undergo laxative-induced bowel cleansing before the procedure.
Less accurate for smaller lesions; better patient scores for comfort, exam preparation.
CT colonography accurately detects cancer and precancerous polyps in persons aged 65 years and older.
Offering CT colonography improved participation in colorectal cancer screening by more than 50% compared with colonoscopy, but colonoscopy identified significantly more advanced neoplasia.
Computed tomographic colonography (CTC) is gaining a foothold in US hospitals despite lack of Medicare coverage or national consensus on its role in colorectal cancer screening.
