Diagnostic Tests for Vascular Conditions

Diagnostic Tests for Vascular Conditions

Miami Cardiac & Vascular Institute offers a wide range of vascular diagnostic services. Our experienced doctors can diagnose an aneurysm, stroke, peripheral artery disease and other conditions affecting your arteries or veins. Our goal is to improve your vascular health and quality of life.

Convenient Testing

Diagnostic testing is convenient. Most tests are minimally invasive and done on an outpatient basis. The Institute offers a wide range of vascular diagnostic tests, including:

  • MRI. Like magnetic resonance imaging used elsewhere in the body, this technology creates pictures of your blood vessels using magnets and radiofrequency waves. Results can show plaque buildup and any structural changes to your arteries or veins that could improve with treatment.

  • MRA. Magnetic resonance angiography uses magnets and radiofrequency waves to create both still and moving images of your blood vessels. MRA helps physicians detect any abnormal changes in blood flow.

  • CT. Contrast dye is added to your bloodstream to make your vessels easier to see. Then a computed tomography scanner takes X-ray images and puts them together into a 3-D picture of your blood vessels.

  • CTA. CT angiograms are highly detailed pictures that show any unusual blood flow through your vessels. Institute physicians use results to determine which treatment is most appropriate for you, such as endovascular therapy or traditional surgery.

  • Echocardiography. This test uses sound waves (ultrasound) to show the size and structure of your heart and heart valves. Images are stored in a computer for later review by an Institute physician.

Noninvasive Vascular Laboratory Testing

One of the distinct advantages of coming to the Institute is our Noninvasive Vascular Laboratory. Our physicians and staff offer many additional noninvasive diagnostic tests in this state-of-the-art setting.

The following tests use sound waves (ultrasound ) to create images or measure blood flow noninvasively in different parts of the body. At the start of your procedure, a technologist applies a small amount of gel and then gently moves a small device, a transducer, across the skin. The transducer sends and receives sound waves to create pictures that are stored in a computer. A physician later reviews the results.


  • Abdominal Doppler Study. This test evaluates the circulation in the arteries and veins of your stomach, intestines, liver, pancreas and spleen.

  • Carotid Ultrasound. This examination checks for any narrowing or blockage in your carotid artery, a major vessel in the neck that carries blood to the head and neck.

  • Transcranial Doppler. This test measures blood flow through the arteries of the brain.

  • Venous Ultrasound. This procedure measures blood flow through the veins in your arms or legs.

Arterial Blood Flow Testing

The Institute’s Peripheral Vascular Laboratory also offers noninvasive arterial studies. This test does not use ultrasound. Instead, a technologist wraps pressure cuffs around your legs and arms, then measures the blood pressure in your arteries at different points along your extremities, in some cases while you walk on a treadmill.

We’ll provide your physician with the results of any of these diagnostic vascular tests. We can also make your next appointment at one of the Institute’s conveniently located facilities throughout South Florida.
