Brief Summary:
to evaluate the acceptability of CT-colonography compared to colonoscopy for the detection of advanced adenomas in subpopulations at high risk of colorectal.

Condition or disease Intervention/treatment Phase
Colorectal Cancer Procedure: Colonoscopy Procedure: CT-colonography Not Applicable

Detailed Description:
Secondary objective: to evaluate the medical and economic impact of the implementation of CT- colonography in this setting.Methodology: prospective multicenter randomized controlled trial with direct patient benefitN° of patients to be included: 600 Study follow-up :1 consultation and 3 phone contacts (M1, M6 and M12)Evaluation criteria:Main endpoint: acceptability of the colorectal cancer screening (% of enrolled patients having actually undergone the exploration)Secondary endpoints: - cost/effectiveness ratio of the 2 diagnostic tests with calculation of the economic and medical costs. - number of advanced adenoma detected in each group- number of CRC cases detected in each group
