and requires no special preparation. You should eat normally and follow the normal dosage of your prescribed medications unless your doctor gives instructions to do otherwise. Dress in loose, comfortable clothes with no metal snaps, zippers, etc.
- If you are pregnant or have anything metallic in your body, please let us know-the exam may not be safe for you. Click here for more information.

CT Scan Preparation
- Preparation can vary according to the type of CT exam and your medical history. AHI will provide full instructions before your exam.
- At the time of scheduling, let our staff know if you are allergic to iodine. If so, we will specify appropriate pre-medication procedures for you to follow 12 to 24 hours before your exam.
- Let us know if you have limited kidney function or kidney failure, a history of heart disease, any personal history of cancer or diabetes, asthma, and current drug prescriptions.
- Your doctor may want you to receive a special contrasting agent before your exam. We will either inject a special fluid into your veins or provide it to you to ingest orally. If it is administered orally, we will ask you to arrive earlier.
- If you will be receiving a contrast agent (by either method):
- It is very important to adequately prepare your body by thoroughly hydrating yourself, beginning a few days before your scheduled appointment. Continue to drink plenty of water-based liquids after your exam.
- Other than a very light breakfast of juice and plain toast, do not consume any meal for four hours prior to your scheduled time.
