UT Southwestern Medical Center’s Cardiac Imaging Program provides patients with comprehensive imaging and diagnostic services for disorders of the heart and its arteries, including coronary heart disease, congenital heart disease, valvular heart disease, cardiomyopathies, diseases of the aorta, and microvascular obstructions.
Technologies such as computed tomography (CT) scans, magnetic resonance imaging (MRI), and multiple gated acquisition (MUGA) scans are used to visualize the heart and assess its functionality. These advanced imaging tools allow physicians and specialists to make the most accurate diagnoses and prescribe targeted treatments and therapies.
Cardiac magnetic resonance (CMR) is a noninvasive cardiac imaging procedure that uses a powerful magnetic field to provide an accurate assessment of heart structure and function. It does not involve the use of radiation and can provide excellent images in patients who are not well imaged using other techniques.
CMR is particularly useful in evaluating the pericardium (the lining around the heart), cardiomegaly (enlargement of the heart chambers and walls), tumors involving the heart, stenotic or regurgitant (narrowed or leaking) heart valves, and the aorta. It also provides excellent visualization of the cardiac structure and function in patients with congenital heart disease.
Coronary CTA, also called coronary calcium scoring, provides pictures of the arteries of your heart. Doctors use the images to look for calcium deposits in the coronary arteries. Calcium deposits can narrow the arteries and increase your risk of heart attack.
