Cardiac Imaging

Cardiac imaging comprises several different procedures that capture pictures of the heart’s structure or function. Doctors use these tests to help diagnose heart conditions and choose the best treatment for patients.

Cardiac imaging tests are common, with doctors performing more than 20 million procedures per year in the United States. 

Pioneers in Cardiac Imaging

UT Southwestern Medical Center is a nationally recognized leader in the development and use of sophisticated cardiac imaging techniques to diagnose and aid in the treatment of heart disease.

We pioneered the development of rapid cardiac MRI, an advanced diagnostic technology that uses modified MRI systems to provide moving pictures of a beating heart.  

Our team of physicians reviews test results thoroughly, making careful treatment recommendations based on all available information. Our skill is not just in interpreting images but in putting them into clinical practice so that our patients get the best care possible.


We perform a variety of modern heart imaging techniques. Echocardiography is a common procedure that uses ultrasound imaging to create pictures of the heart. Our specialists perform several types of echocardiograms, including: 

  • Stress echocardiogram: This test, often used to detect coronary artery disease, shows how well your heart pumps blood before and after exercise.
  • 3-D echocardiogram: This produces highly detailed images that help assess mitral valve function and congenital abnormalities.
  • Transesophageal echocardiogram: A cardiologist passes a probe down your mouth to your esophagus to get clear images of your heart. A sedative and an anesthetic are used to numb your throat before the test.

Other tests we specialize in include:

  • Nuclear heart scan: In this procedure, a safe, radioactive substance is injected into your bloodstream. Radioactive emissions are detected by a camera outside your body, which captures images of your heart.
  • Cardiac MRI: Magnetic resonance imaging (MRI) uses powerful magnets to deliver detailed images of the heart and surrounding vessels. An advanced form of this test, rapid cardiac MRI, uses modified MRI systems to provide moving pictures of a beating heart.
