Cardiac Imaging

What Is Cardiac Imaging?

Cardiac imaging refers to the range of diagnostic techniques used to visualize the heart’s structure, function, and blood flow without invasive exploratory surgery. These techniques help physicians diagnose heart disease, evaluate heart function, guide treatment decisions, and monitor patients over time.¹
Rather than one single technology, cardiac imaging encompasses several distinct methods, each suited to answering different clinical questions, from the shape and pumping strength of the heart to the presence of blockages in the coronary arteries.¹

Cardiac magnetic resonance imaging is considered the best method to evaluate heart structure, size, and function.

Echocardiography

Echocardiography uses sound waves to create real time images of the beating heart and the blood flowing through it. Because it doesn’t involve radiation and can be performed quickly at the bedside or in an outpatient office, it’s one of the most commonly used cardiac imaging tools for evaluating heart valve function, chamber size, and overall pumping ability.¹

Cardiac CT

Cardiac computed tomography uses X rays combined with computer processing to build detailed three dimensional images of the heart and surrounding blood vessels. It’s particularly useful for evaluating the coronary arteries, helping detect narrowing or blockages that indicate coronary artery disease.¹

Cardiac MRI

Cardiac magnetic resonance imaging uses magnets and radio waves rather than radiation to produce highly detailed images of the heart’s structure and function. It’s widely considered one of the most precise tools for evaluating heart muscle, chamber size, and the major blood vessels, and it allows repeated imaging over time without the radiation exposure associated with some other techniques.¹

Cardiac Catheterization

Cardiac catheterization, sometimes called a heart cath or coronary angiogram, involves threading a thin tube through a blood vessel into the heart to directly visualize the coronary arteries and heart chambers using contrast dye and X ray imaging. Intracardiac echocardiography, a related technique, is also used during certain catheter based procedures to help physicians visualize heart structures in real time and reduce the risk of complications.²

Nuclear Imaging

Nuclear cardiac imaging techniques, including positron emission tomography and nuclear stress testing, use small amounts of a radioactive tracer to evaluate blood flow to the heart muscle and assess how well the heart functions under stress or at rest.¹

Choosing the Right Imaging Technique

Because each cardiac imaging method answers somewhat different clinical questions, physicians often choose a specific test, or combination of tests, based on the suspected condition, whether that’s valve disease, coronary artery blockage, heart muscle function, or an electrical abnormality.³
Advances in imaging technology continue to expand what’s possible, including artificial intelligence assisted image analysis that’s increasingly being incorporated into how cardiac images are interpreted.¹

Why visual communication matters for cardiac imaging?

Because cardiac imaging includes several distinct technologies, each working through a different physical principle, patients and even some clinical trainees often find it difficult to understand why a particular test was chosen over another for their situation.
Medical illustrations and animations can show how each imaging technology works at a basic physical level, compare what each test can and cannot reveal about the heart, and help clarify why a specific combination of tests might be recommended for a given diagnosis.¹
Visual communication can support:

• Comparison of echocardiography, cardiac CT, MRI, and nuclear imaging
• Cardiac anatomy education relative to specific imaging findings
• Catheterization procedure animation
• Patient education on what to expect during specific imaging tests
• Healthcare professional training
• Clinical trial and research communication
• Medical device and imaging technology marketing

Frequently Asked Questions

What is the most common type of cardiac imaging?

Echocardiography is among the most commonly used cardiac imaging tests because it’s quick, doesn’t involve radiation, and provides real time information about heart valve function and pumping ability.¹

What is the difference between cardiac CT and cardiac MRI?

Cardiac CT uses X rays and is particularly useful for evaluating the coronary arteries, while cardiac MRI uses magnets and radio waves and is considered especially precise for evaluating heart muscle structure and function.¹

Is cardiac catheterization the same as an echocardiogram?

No, cardiac catheterization is an invasive procedure that threads a catheter into the heart to directly visualize the coronary arteries, while an echocardiogram is noninvasive and uses sound waves from outside the body.^1,2

Does cardiac imaging involve radiation?

Some techniques, such as cardiac CT and nuclear imaging, involve a small amount of radiation, while echocardiography and cardiac MRI do not use ionizing radiation.¹

How do doctors decide which cardiac imaging test to use?

The choice depends on the suspected condition, since each imaging method is better suited to answering different clinical questions, such as valve function, coronary artery blockages, or heart muscle strength.³

Is cardiac imaging used only for diagnosis?

No, cardiac imaging is also used to monitor known conditions over time, guide certain catheter based procedures in real time, and assess how well treatment is working.^1,2
