Which term is used for recording cardiac structures using ultrasound?

• A. Echocardiogram
• B. Electrocardiogram
• C. Angiogram
• D. Cardiac MRI

Answer: (A)

Ultrasound imaging of the heart is called echocardiography, and the study produced is an echocardiogram. This technique uses high-frequency sound waves to create real-time pictures of the heart’s chambers, valves, and motion, allowing clinicians to assess structure and function, such as chamber sizes, valve openings and regurgitation, and how well the heart pumps (ejection fraction). The other options refer to different tests: an electrocardiogram records the heart’s electrical activity, not its anatomy; an angiogram images blood vessels using X-ray with contrast; and cardiac MRI uses magnetic resonance to visualize heart structures in detail.
