Abstract Objective To determine the positive predictive value (PPV) of ≥ 6 mm polyps detected by CT colonography (CTC) prepared before the test using a low-dose iodinated manure-labeled diet without laxative dose and evaluate the patient’s feelings. Methods One hundred and twenty-two patients with a mean risk received a CTC test that did not prescribe laxatives. A total of 60 mL of diatrizoate and sodium diatrizoate (22.2 g iodine) were stool labeled. Standard diagnostic methods
