Question

A) CT colonoscopy is less invasive than conventional colonoscopy since it doesn't require insertion of a scope into the colon.
B) There is no need for recovery time after CT colonoscopy since it is a non-invasive procedure.
E) Patients with bleeding disorders or those taking anticoagulant medications can safely undergo CT colonoscopy since there is no risk of bleeding, unlike in conventional colonoscopy where tissue biopsies and polyp removals may cause bleeding. However, CT colonoscopy does not allow for polyp removal or biopsies of tissue, which is an advantage of conventional colonoscopy. Bowel preparation is still necessary for CT colonoscopy.
