Cardiac Imaging
At Torrance Memorial, we offer advanced diagnostic technology to identify heart disease at its earliest and most treatable stages. Our state-of-the-art imaging tools can detect problems that may not be found using conventional diagnostic methods.
The Torrance Memorial Cardiovascular Imaging program offers a full range of imaging technologies to diagnose heart disease, plan appropriate care and confirm that treatment is complete. We also use diagnostic imaging for pre-surgical planning to help minimize complications during catheter-based procedures and heart surgery.
Cardiac Computed Tomography (CT)
A cardiac CT scan measures the coronary artery calcium score. This noninvasive test provides information about the location and extent of calcified plaque in the coronary arteries, which supply blood to the heart muscle.
Plaque is a buildup of fat and other substances, including calcium. Over time, plaque can narrow the arteries or block blood flow to the heart, potentially causing chest pain, also known as angina, or a heart attack. Because calcium can be a marker of coronary artery disease, the amount detected during a cardiac CT scan can provide helpful diagnostic information.
Coronary Computed Tomography Angiography (CCTA)
Coronary computed tomography angiography, also called CCTA, is a noninvasive test used to examine the arteries that supply blood to the heart muscle. During the test, contrast dye is injected through an intravenous line to help create detailed images of the heart and blood vessels.
In some cases, CCTA may eliminate the need for a coronary angiogram, which is a more invasive procedure that may require sedation, catheter insertion and a longer recovery period. At Torrance Memorial, radiologists with specialized training and certification interpret these scans.
Cardiac Magnetic Resonance Imaging (MRI)
Cardiac magnetic resonance imaging, also called cardiac MRI or CMRI, is a noninvasive diagnostic test that does not use ionizing radiation. It allows physicians to obtain detailed images of the heart and surrounding structures.
Cardiac MRI can help diagnose heart disease, heart attack damage, scarring, tumors and heart valve conditions. It can also be used to examine blood vessel abnormalities and measure blood flow through the aorta and aortic valve.
Cardiac Positron Emission Tomography (PET)
A cardiac positron emission tomography scan, also called a cardiac PET scan, evaluates blood flow to the heart and can help assess damage to the heart muscle following a heart attack.
During the test, a small amount of radioactive tracer is injected into a vein. A specialized camera detects the tracer and creates computer-generated images of the heart. These images can help determine whether the heart receives enough blood during activity and at rest.
Echocardiogram
An echocardiogram, sometimes called an echo, is a noninvasive procedure used to evaluate the heart's structures and function. During the procedure, a device called a transducer sends high-frequency sound waves through the chest toward the heart.
The sound waves bounce, or echo, off the heart's structures and are sent to a computer. The computer uses this information to create moving images of the heart walls and valves.

Nuclear Cardiology
A nuclear stress test allows physicians to view images of the heart while a patient is resting and after exercise or medication that makes the heart work harder.
The test provides information about the size of the heart's chambers, how effectively the heart pumps blood and whether the heart has damaged tissue. It can also help physicians determine whether coronary arteries are narrowed or blocked because of coronary artery disease.
How Will You Learn About Your Results?
The technologist performing your test cannot provide or interpret the results. A radiologist or other qualified physician must first review the images and prepare an official report.
The report will be sent to the physician who ordered your test. Your physician will discuss the results with you and explain any recommended next steps.
