1. Understand the principles of stool tagging for virtual colonoscopy examinations. 2. Learn how to administer an iodinated-contrast enema and colonic insufflation with a single rectal intubation. 3. Realize the advantages of performing stool tagging via a rectal enema compared to oral administration of contrast agents.


1. Review of conventional methods employed for stool tagging. 2. Method and apparatus required to administer an iodinated water-soluble contrast enema in conjunction with gas insufflation of the colon. 3. Comparison of results from virtual colonoscopy patients who had received rectal versus oral routes of administration of iodinated-contrast agents.


The benefits of using an enema route of contrast administration for stool tagging are that it significantly reduces the time required to achieve opacification of liquid feces and that it achieves a more uniform distribution of contrast material compared to an oral route of administration.
