CT Colonography

The most important part of any CT colonography happens before you come to the S. Mark Taper Foundation Imaging Center. To get a good look at the lining of the colon, it is necessary to clean out any traces of food or other material.

This means you must maintain a restricted diet the day before your exam and take colon-cleaning medications.

A prep-kit with detailed instructions and the medication you need to take before your exam is available from us.

You can either pick up this prep-kit in person, or request that it be mailed to you. To request a prep-kit, or for more information, call (310) 423-3266.
