Angiogram Testing

If your doctor recommends an angiogram, you're in good hands at Banner Health. We offer both catheter-based and CT angiograms as part of our advanced imaging services. These tests help us understand how blood flows through your blood vessels so we can accurately diagnose your condition and recommend the best treatment, including angioplasty and stenting when needed.

Early detection can help you avoid serious heart problems. Schedule your angiogram consultation with Banner Health today.

If you're experiencing symptoms like chest pain, shortness of breath or dizziness, don't wait. Early testing can help detect arterial disease and may prevent a heart attack or stroke.

What is an angiogram?

An angiogram is an imaging test that helps your doctor examine the flow of blood through your arteries and veins. It is commonly used to detect arterial disease, blood clots and narrowed or blocked blood vessels.

There are two main types of angiograms:

• Catheter-based angiogram (coronary angiography): This minimally invasive test is used to examine the arteries around your heart. A thin flexible tube called a catheter is inserted into an artery, usually in the groin. As a special dye (also called a contrast agent) is injected, real-time X-ray images are taken to detect blockages or other issues with blood flow. If needed, angioplasty and stenting can be done during this procedure.
• CT angiogram (CTA): This non-invasive option uses a CT scan and contrast agent to create detailed images of your blood vessels. It’s often used to detect aneurysms, arterial disease or other concerns in the chest, neck, brain or heart.

When is an angiogram used?

Your doctor may recommend an angiogram if you have:

• Ongoing or unexplained chest pain
• Symptoms of a heart attack or stroke
• A suspected aneurysm or blood clot
• Signs of arterial disease or narrowed arteries
• A known condition that affects blood flow

An angiogram can help diagnose problems and also guide treatment. For example, angioplasty and stenting may be performed at the same time to improve blood flow in blocked blood vessels.

How to prepare for an angiogram

Your care team will give you specific instructions. In general:

• Eating and drinking: You may be asked to avoid food and drink for 6 to 8 hours before the test.
• Medication: Some medications may need to be adjusted. Talk with your doctor before stopping any prescriptions.
• Breastfeeding: Pump milk ahead of time. Wait 24 hours after the test before nursing again, due to the contrast agent.
• Hospital gown: You’ll wear a gown to allow access to the area where the catheter is inserted.

What to expect during an angiogram

Most angiograms are done in a hospital setting. You may be given medicine to help you relax. A local anesthetic will be used to numb the area where the catheter is inserted, often in the groin or wrist.

A thin flexible tube is carefully guided through your blood vessels to the area being examined. When the contrast agent is injected, X-ray images are taken to show how blood moves through your body.

If needed, your doctor may do angioplasty and stenting during the procedure. This can open narrowed arteries and restore blood flow.

Once the test is done, the catheter is removed, and pressure is applied to the site to help prevent bleeding. You'll need to lie flat for several hours afterward and arrange for someone to drive you home.

Are there risks or side effects?

Side effects from an angiogram are rare. The most common is bruising or mild tenderness where the catheter is inserted.

Let your provider know about any allergies, especially to contrast dye, or if you have kidney problems. Our team will take all necessary steps to keep you safe and comfortable during the procedure.

Frequently asked questions about angiograms

What is an angiogram used to diagnose? 

An angiogram helps detect arterial disease, narrowed or blocked blood vessels, blood clots, and causes of chest pain, stroke or heart attack symptoms.

Is an angiogram painful or uncomfortable?

You’ll receive medicine to help you relax, and the site where the catheter is inserted will be numbed. Most people feel little to no pain during the test.

How long does an angiogram take?

The test typically takes 15 to 60 minutes. If angioplasty and stenting are done at the same time, the procedure may take longer.

What happens after the catheter is removed?

After the catheter is removed, pressure is applied to help prevent bleeding. You’ll need to rest flat for several hours and avoid strenuous activity.

Can I go home the same day?

Yes, most angiograms are outpatient procedures. You’ll need someone to drive you home.

Is it safe to have an angiogram while breastfeeding?

If you're breastfeeding, pump ahead of time. Wait 24 hours after the test before nursing again to allow time for the contrast agent to leave your system.

What is the difference between a CT angiogram and a catheter-based angiogram?

A CT angiogram uses a CT scan and dye to take pictures of your blood vessels without inserting a catheter. A catheter-based angiogram uses a tube placed inside your artery to inject dye and take X-ray images in real time. Your doctor will recommend the best test for your symptoms and health history.
