Preparing for an Abdominal CT Scan

Do not eat or drink anything four (4) hours prior to examination. Thirty minutes before exam, drink one bottle of oral CT contrast.  This contrast is available at our Front Desk, or often is given to you by your healthcare provider when the exam is scheduled.


If the exam is scheduled after 9 a.m., drink one bottle of oral CT contrast three hours prior to the exam time.  Do not eat anything after the first bottle of oral CT contrast. Thirty minutes prior to the exam, drink a second bottle of oral CT contrast.


If intravenous contrast is needed, it will be administered at the start of the exam. Patients may experience a warm sensation throughout the body after the contrast injection and a metallic taste in the mouth. These sensations typically disappear in a few minutes.
