Other Contrast
 | 1. Do we ever use rectal contrast and if so when and why? |

Rectal Contrast: Virtual Colonoscopy One other application of rectal contrast is in virtual colonoscopy. This is a unique application and in this case room air or CO2 is placed in the colon for distention. With virtual colonoscopy the patient is prepped for the study with cleansing agents and a specific prep is used. Please see the section on virtual colonoscopy. |
