Single-center, prospective, non-randomized clinical trial designed to evaluate the technical feasibility during CCE procedure, when using MB-MMX as a contrast- enhancement technique of mucosal staining in CRC high risk population.~Subjects will undergo a bowel preparation (single dose, 4L PEG), including 200 mg Methylthioninium chloride, corresponding to eight 25 mg MB-MMX tablets and 1 tab of Resolor (Prucalopride 1mg). An experienced Gastroenterologist will read the CCE procedure and complete a subjective questionnaire, to evaluate mucosal enhancement during a CCE procedure, when using MB-MMX as a contrast-enhancement technique.
