Cardiovascular Imaging

Cardiac MRI

Cardiac MRI is an exciting and new way of using MRI to image the heart. Magnetic resonance imaging is a non-invasive medical test that helps physicians diagnose and treat medical conditions. It does this without using any radiation.

Cardiac MR imaging uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of the heart.

Cardiac MRI is performed to help:

Cardiac MRI is performed at Bellin Health MRI. 740 S. Van Buren St. in Green Bay, just behind Bellin Hospital.

Cardiac CT

In the past several years, a technology revolution has allowed 3 dimensional imaging of the live, beating heart using CT (“CAT scan” or Computerized Tomography). This is a non-invasive method of imaging the heart and vascular system in 3 dimensions using x-rays. The power of modern CT scanners makes it possible to acquire detailed information on coronary artery anatomy, heart structure and function and anatomy of the great vessels. The speed of the scanner allows imaging within a few seconds. The study requires special computer processing and analysis. Cardiology Associates’ interpreting physicians are specially credentialed in cardiac CT. We interpret all cardiac CT studies performed at Bellin Health Hospital Center. As with all x-ray studies, patients are exposed to some radiation.  As scanners have improved, the dose to patients has reduced, however radiation exposure needs to be considered as part of the very small risk of the study.


Echocardiography is a non-invasive imaging test of the heart in which pictures are acquired using ultrasound waves. There is no radiation risk for this kind of test. The information gives detailed analysis of structure and function of the heart.

There are two types of echocardiograms:

What to expect (for your TEE)
During the test you will be given an intravenous sedative to make you comfortable. In most patients, transesophageal echocardiograms are performed with very low risk and the details of the test will be reviewed with you by our cardiologist and the staff. All patients are closely monitored by medical professionals throughout the test. As with any test involving sedation, patients are also monitored for a period of time after the test to make sure they have fully recovered.


Nuclear Imaging

Stress testing is used to assess blood flow to the heart to evaluate for any possible blockages in the arteries feeding the heart. This is done to evaluate symptoms or to work up certain heart conditions. In situations where patients are unable to walk on a treadmill, medication is given through an IV to stress the heart. A nuclear stress test is used to gather information about how well your heart works during physical activity and at rest. This testing involves a special substance given through an IV that becomes visible on images taken by a special camera. It examines blood flow to the heart muscle and identifies any areas of damage.
