Cardiovascular Imaging

Sharon Reimold, M.D., a heart imaging cardiologist at UT Southwestern, studies an image.

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

These include rapid cardiac MRI, an advanced diagnostic technology developed at UT Southwestern that uses modified MRI systems to provide moving pictures of a beating heart.

Single Photon Emission Computerized Tomography, or SPECT, is another cardiac imaging technology pioneered at UT Southwestern that is used to monitor blood supply to the heart using three-dimensional images.

Other Cardiovascular Imaging Techniques

Cardiac Catheterization

In a cardiac cath procedure, a cardiologist painlessly places a thin flexible tube (catheter) inside your heart for diagnostic examination and treatment. Cardiac catheters also may be used to administer a drug or unblock narrowed coronary arteries with balloon angioplasty or stents.

Computed Tomography (CT)

CT combines X-rays and computer technology so a radiological specialist can deliver detailed, cross-sectional views of internal organs and structures, including the heart and surrounding arteries. Coronary CT angiography uses contrasting dyes to deliver even greater detail about your heart and related arteries.


Echocardiography is a diagnostic method using ultrasound that a sonographer will use to record and monitor your heart’s function and the action of its valves. The echocardiogram is a noninvasive procedure that provides images of your heart’s valves and chambers. It can be used to determine the presence of disease and measure the effectiveness of treatments.

Electrophysiology (EP)

EP is a technology that a cardiologist will use to diagnose and treat abnormal heart rhythms, or arrhythmias, through the placement of electrodes inside the heart. An EP examination records the electrical activity of your heart and can be used to explore rhythm abnormalities and to determine and administer effective treatments.


Magnetic resonance imaging (MRI) uses powerful magnets (as opposed to radiation such as X-rays) so a radiological specialist can deliver detailed images of the heart and surrounding vessels.

Positron Emission Tomography (PET)

PET uses radioactive dyes so a radiological specialist can create detailed three-dimensional images of the heart. PET can also be used to monitor blood flow as well as assess the heart’s condition.
