Non-invasive heart testing


Noninvasive heart testing helps our team discover, diagnose, evaluate and treat heart conditions. Most cardiac tests can be performed at our hospitals or ambulatory offices located throughout the region.

Why choose us?

Using the latest technology, our world-class experts work closely with patients to prevent, diagnose and treat heart diseases and disorders. We use high-definition and 3-D images of your heart to provide a treatment plan tailored to your specific needs.

Our cardiac sites are accredited for echocardiography by the Intersocietal Accreditation Commission (IAC). This accreditation follows an extensive evaluation including case studies, testing procedures, equipment and training practices, and demonstrates our commitment to high-quality echocardiography in diagnosing cardiovascular disease.


We offer advanced noninvasive imaging for heart and vascular disease and disorders using the most sophisticated equipment available today. We offer a wide variety of technologically advanced, precise imaging tools to create pictures of and effectively care for your heart and circulatory system.

Our cardiovascular imaging specialists work with you to determine the most accurate tests to view and assess your heart and vascular function, which can include:

  • Cardiac MRI : This imaging method uses powerful magnets and radio waves to create pictures of the heart. It does not use radiation (X-rays).
  • Cardiac CT scan: A computed tomography (CT) scan of the heart is an imaging method that uses X-rays to create detailed pictures of the heart and its blood vessels.
  • 640-slice CT scan: This is a CT scan performed at North Shore University Hospital using one of the most advanced and fastest scanners available.
  • Echocardiogram (echo) : This test that uses sound waves to create pictures of the heart. The picture is more detailed than a standard X-ray image. An echocardiogram does not expose you to radiation.
  • Stress echocardiogram: Stress echo is done as part of a stress test, when you exercise or take medicine from your doctor to make your heart work hard and beat fast. A technician will use echo to create pictures of your heart before you exercise and as soon as you finish.
  • Electrocardiogram (EKG): Also also called an EKG or ECG, this is a simple, painless test that records the heart's electrical activity. Each heartbeat sends an electrical signal from the top of the heart to the bottom. As it travels, the signal causes the heart to contract and pump blood. The process repeats with each new heartbeat.
  • Transesophageal echocardiogram (TEE): This is an echo test that involves a flexible tube (probe) with a transducer at its tip. Your doctor will guide the probe down your throat and into your esophagus (the passage leading from your mouth to your stomach). This approach allows your doctor to get more detailed pictures of your heart because the esophagus is directly behind the heart.


Our tests are designed to provide a picture of how well your heart and is functioning, allowing our physicians to reach a quick and accurate diagnosis, allowing them to develop the best treatment path. These tests include:

  • Carotid Doppler study
    This painless and harmless test uses high-frequency sound waves to create pictures of the insides of your carotid arteries.

  • Coronary calcium scoring  
    This test looks for specks of calcium in the walls of the coronary (heart) arteries.

  • Event monitor testing
    A medical device records the heart's electrical activity, usually to diagnose arrhythmias.

  • Exercise stress testing
    Tests are done on your heart as you exercise (walk or run on a treadmill or pedal a stationary bike) to make your heart work hard and beat fast.

  • MUGA scan (multi-gated acquisition scan)
    Also known as nuclear ventriculography, this test uses radioactive materials called tracers to show the heart chambers. The instruments do not directly touch the heart.

  • Nuclear stress testing
    This test shows how well blood flows into the heart muscle, both at rest and during activity.

  • Tilt-table testing
    This simple test detects causes of fainting or lightheadedness.
