Fast, Accurate Imaging, When You Need It Most
Computed Tomography Angiogram (CTA)
A Computed Tomography Angiogram or CTA scan is an imaging test that combines computers and 360-degree x-rays to produce highly detailed images of the blood vessels of the body. CT Angiography is commonly performed to evaluate for blood vessel disorder problems such as aneurysms (balloon like bulging), stenosis (narrowing), dissection (wall splitting), malformations or fistula (abnormal vascular connections). These conditions can occur in the brain, neck, spine, chest, abdomen (such as liver and kidneys), and legs.
Tell your doctor if allergic to Iodine or Xray contrast
-
Tell the technologist if you have a history of Kidney disease
-
Tell the technologist if you are on Metformin or Glucophage for diabetes control.
-
Tell your doctor/technologist if you are, or suspect you might be pregnant.
-
Do not eat or drink for four to six hours prior to your exam
-
If you have a history of kidney problems or diabetes, blood tests (creatinine, blood urea nitrogen) will be done before the CT scan to check that your kidneys are functioning properly prior to giving the IV contrast.
If you are allergic, medication can be prescribed by your physician prior to the testing.

A registered technologist will discuss the procedure with you and answer any questions you may have. The technologist will go over a list of questions regarding your medical history. To ensure the quality of your exam you may be asked to change into a gown and remove all metallic items from your body, such as your watch, bra, jewelry, hairpins, glasses, and hearing aids.
This test requires IV contrast administration. A dye that contains iodine (contrast material) is injected into a vein during the scan. The contrast allows blood vessels and certain structures to enhance and become for visible on the CT images.
You may feel a warm sensation throughout the body or have a metallic taste in your mouth. This is all normal.
The technologist will position you on the exam table in a donut-shaped gantry. At times during the exam, the table will move, and you will hear the sound of the x-ray tube circling your body. At all times, the technologist will be able to see you and communicate with you on a two-way intercom. Most procedures take approximately 45 minutes including the time needed to prepare you for the exam.
After your CT scan, you may resume your normal activities, diet, and medications, unless instructed otherwise by the technologist or your doctor. Any contrast given for your exam will be eliminated in a day or two, and it is important to drink a lot of water if you have had a contrast CT exam.
Your examination will be reviewed and reported on by a radiologist, and the results will be sent to your doctor.
