Fig. 4. Bar graph illustrates responses to follow-up questionnaire
from patients undergoing multidetector CT colonography (white bars)
and colonoscopy (black bars) (n = 91 replies). Significantly
more patients tolerated CT colonography well than tolerated colonoscopy well.
Patients expressing a preference (n = 55) significantly preferred CT
colonography to colonoscopy; and of those expressing an opinion (n =
60), significantly more found CT colonography more acceptable (p <
0.005 [asterisks]).
