Cardiovascular Imaging

The Echocardiography Laboratory, the Nuclear Cardiology Laboratory, and the ECG Laboratory offer a full range of ECG monitoring and non-invasive imaging services. The Echocardiography Laboratory is certified by the Intersocietal Commission for the Accreditation of Echocardiography Laboratories. Hennepin Healthcare provides advanced, state-of-the-art cardiac imaging.

Procedures & Treatments


Echocardiography is a painless test that uses sound waves to create moving images of your heart. The images show the size and shape of your heart, as well as your heart's chambers and valves.

Echocardiography can show areas of the heart muscle that aren't working well due to poor blood flow or damage from a previous heart attack. Doppler ultrasound, a type of echocardiography, shows how well blood flows through your heart's chambers and valves.

Additional benefits of echocardiography include the ability to detect blood clots inside the heart, fluid buildup in the sac surrounding the heart, and problems with the aorta, the main artery that carries oxygen-rich blood from your heart to your body.

Nuclear cardiology laboratory

Noninvasive techniques are used in the Nuclear Cardiology Laboratory to assess heart blood flow. Among the most used procedures of nuclear cardiology, Myocardial Perfusion Imaging can show areas of the heart muscle that aren’t getting enough blood flow as well as if you’ve recently had a heart attack. This test is also called a nuclear stress test. It can also show how well the heart muscle is pumping.

Electrocardiogram laboratory

An electrocardiogram, or ECG, is a test that records the electrical activity of your heart.

Coronary computed tomography angiography

Cardiac computed tomography angiography is an imaging procedure that uses a computed tomography scanner to look at the structures and blood vessels of the heart. These scanners are used to view blood vessels in the body.

Cardiac magnetic resonance imaging

Cardiac Magnetic Resonance Imaging creates both still and moving images of your heart and major blood vessels. Doctors use cardiac MRI to see images of the beating heart, its structure, and function. These images can help them decide the best way to treat patients with heart problems.
