• Computerized Tomography Angiography (CTA)

1. What is computerized tomography angiography?
   Computerized Tomography Angiography is an advanced imaging technique which uses a computer and x_rays to visualize blood flow.

   The scan requires the IV injection of the contrast media.
   Injection of the contrast may cause a local feeling of warmth. Reactions are rare but it is extremely important to report any concerns to the technologist.

   The patient should not eat or drink for at least 6 hours prior to the scan.
   
   Medications may be taken with a small amount of water during this time.
   
   It is extremely important to report any allergies or previous reactions to medications to the physician, nurses, or x-ray personnel.
   
   A radiologist will evaluate the test and prepare a report to be sent to your doctor. It may take several days to receive this report from your doctor.
