CT Angiogram: Diagnosing Peripheral Artery Disease

CT angiogram (CTA) is a non-invasive imaging procedure that combines computed tomography (CT) scanning with a contrast dye to produce detailed images of blood vessels and tissues. This technique allows doctors to see inside the arteries and assess their health, making it a critical imaging tool for diagnosing peripheral artery disease (PAD). By providing clear, high-resolution images, CT angiograms help in detecting blockages, evaluating blood flow, and planning appropriate treatments.

CT Angiogram Candidates

Patients at risk for PAD, especially those over the age of 50 with risk factors such as diabetes, high blood pressure, high cholesterol, smoking, or a family history of PAD, should consider a CT angiogram. If you are also experiencing the following symptoms, you should consider taking this test.

  • Leg pain while walking (claudication)
  • Leg cramps at night (rest pain)
  • Sores on toes or feet that won’t heal
  • Coldness in the legs or feet
  • Discoloration in the legs or feet

Benefits of the CT Angiogram

A CT angiogram provides many advantages for individuals who are at risk of or are experiencing symptoms of PAD.

  • Non-invasive tests reduce the risk of bleeding and infection
  • Provides highly detailed 3D images of the arteries
  • Detects PAD at an early stage 
  • Typically takes under 30 minutes
  • More comfortable experience for patients

CT Angiogram Preparation

Before the procedure, you will receive specific instructions on how to prepare for your CT angiogram, which may include the following:

  • Do not exercise 1 hour before the test
  • Do not eat or drink anything with caffeine 
  • Do not smoke or drink alcohol 1 hour before the test
  • Wear loose and comfortable clothing 
  • Continue to take your regular medications that day unless instructed otherwise

CT Angiogram Procedure

A CT angiogram requires injecting a contrast dye into the blood vessels. The CT scanner takes multiple cross-sectional images, which are then reconstructed by a computer to create a three-dimensional view of the blood vessels. The scan is quick, usually taking about 15-30 minutes, and involves the following steps:

  • IV Insertion: A nurse or technician will insert a thin plastic tube (IV) into a vein in your arm or hand.
  • Contrast Dye Injection: A contrast dye will be injected through the IV line. This dye helps blood vessels show up more clearly in the CT scan images, You might experience a warm flushing sensation or a metallic taste in your mouth during injection, which is usually temporary and harmless.
  • Positioning: You’ll be positioned on a special scanning table that slides into the CT scanner, a large donut-shaped machine. Depending on the area being examined, you might be positioned on your back or stomach.
  • Scanning: The CT scanner will rotate around you, taking multiple X-ray images at different angles. During the scan, you’ll need to lie still and you may be asked to hold your breath for brief moments to ensure clear images.

Once the scan is complete, the IV line is removed, and you can resume your normal activities. It is important to drink plenty of fluids to help flush the contrast dye from your system. There is minimal downtime associated with a CT angiogram, and most patients can return to their usual activities immediately.

Understanding Your Results

Our affiliated vascular specialists are interventional radiologists who will review the images from your CT angiogram. One of our interventional radiologists will assess the arteries in your legs for any blockages caused by plaque buildup. They will measure the degree of narrowing in the arteries and pinpoint the exact location of any blockages. The CTA images will show how blood flows through your arteries. If there are signs of a blockage or reduced blood flow, it can be a sign of PAD. Depending on the results, your doctor may recommend treatment options such as medication to manage symptoms and prevent further progression of PAD, lifestyle changes, and minimally invasive treatments to open up narrowed arteries, like angioplasty and stenting.

Why is a CTA Scan Important?

A CT angiogram (CTA) scan is important for the diagnosis and management of PAD. It provides an accurate diagnosis with highly detailed 3D images of blood vessels. This allows doctors to pinpoint the exact location, severity, and extent of blockages in the arteries.

This accuracy is crucial for differentiating PAD from other conditions and determining the best course of treatment. A CTA scan can also help detect complications of PAD early to prevent further issues.

CT Angiogram Frequently Asked Questions

Can a CT angiogram detect blockage?

A CT angiogram is highly effective in detecting blockages in blood vessels. The contrast dye makes blood vessels visible on the CT images, showing the presence of blockages, narrowing, or other abnormalities.

How soon will I know the results of my CTA?

Your results might be available shortly after the scan, but a detailed analysis by a radiologist can take a few days. Your doctor will review the results with you once they are available.

How does CTA compare to a traditional angiogram?

CTA is less invasive than traditional angiography, which involves inserting a catheter into the blood vessels. CTA uses CT imaging and contrast dye injected into a vein, making it quicker and generally safer with a lower risk of complications.

I like the doctor they were kind of pretty thorough he says that he could help me he found out the filter in my abdomen from the surgery I had in 1996 has been clogging my blood flow for 25 years and that’s causing the swelling at every other doctor told me was lymphedema it was not lymphedema it caused the lymphedema because no other doctor took the time or care enough to find out the reason for my leg swelling this doctor was the only one who finally found out and he’s going to see if you could put a stent inside the filter to open it up and and stop my legs from swelling hopefully this will all go good it hasn’t happened yet but I’ll keep you posted thankful for this docto I just pray and hope that it works otherwise I like the doctor very much

I had a good experience with my procedure and Dr. Mobley’s follow-up calls are great. I’ve never had a doctor who has been so concerned about following up after a procedure to see how I’m doing and if there are any post-procedure problems I may have experienced (which there aren’t). I’d highly recommend Dr. Mobley.

He puts his patients before himself, returning calls and e-mails quickly. Not only is he kind and considerate, he is an excellent physician. I had to have a procedure that requires me to be awake, and he talked me through it and kept me at ease. If I could give him more stars, I would.
Super friendly, tentative, once in the procedure rm the sx staff made you feel comfortable, easy,+ answered all questions. David mobley, MD answered all my questions, very informative, caring. I felt confident in his care

This was the best experience I have had in such a long time and I have had quite a few procedures in the past both in patient and out including the procedure I was currently present for. No other surgeon has been so kind, transparent, and gentle. Not only did he personally come out beforehand to provide me with education on my procedure, but he talked me through every step of the way and made me feel so comfortable and relaxed. Not to mention his amazing staff! Despite being extremely nervous they kept me smiling and laughing throughout the whole process. 10/10 would recommend. Thank you so much guys!!
