Computed Tomography Angiography (CTA) |
|
|
CTA is a safe and accurate method of acquiring detailed images of the vascular system (your blood circulatory system). CTA is used as an alternative to MRA when a metal stent has already been placed in the area to be studied, or if you have an implanted metal device, such as a pacemaker. CTA technique is used to image the arteries of the brain, carotid arteries, aorta, renal arteries, and vessels of the extremities.
Patient Experience
The examination will take approximately 30-60 minutes to complete, depending upon the information requested by your healthcare provider. After you arrive, you will have a brief discussion with a highly skilled CT technologist and if necessary, an intravenous (IV) will be started in a vein in your arm. You will begin your exam by lying on the CT scan table. For the best quality image, you need to be as still as possible during the exam. Just relax and breathe normally. The table moves slowly through the ring-shaped CT scanner as the images are taken. The technologist is always nearby to assist you.
Contrast and Allergic Reactions
Depending upon the type of exam, you may be given a contrast agent through an IV in a vein in your arm. For your comfort and safety, Suburban Imaging only uses non-ionized contrast, a safe FDA-approved contrast agent. If you have a known contrast allergy, please notify the technologist, who will confer with the radiologist as to whether you can be given IV contrast at Suburban Imaging. If it is determined that you can have a study at Suburban Imaging, the radiologist will determine if pre-medication is indicated. We have pre-medication available.
After Your Exam
Your CT images will be interpreted by a board certified radiologist and the findings will be reported to your healthcare provider. Your healthcare provider will contact you to discuss the results.
CTA is available at: Coon Rapids, Centennial Lakes and Burnsville |
