Most CT exams do not require preparation. The exceptions are studies involving the abdomen or pelvis, Colonography, and CTs which are done along with a PET exam. See below for the prep information for these exceptions:
For CTs involving the abdomen and/or pelvis
- Do not eat or drink for three hours before your exam.
- You may take medications with a small sip of water.
If you are having a full body CT scan, you can print out the CT Whole Body Screening Questionnaire , complete it and bring it with you to speed up the registration process.
