What is the term for an echocardiogram that uses sound waves to create an image of the heart?

The term for an echocardiogram that uses sound waves to create an image of the heart is accurately referred to as a cardiac ultrasound, also known as an echocardiogram. This procedure employs high-frequency sound waves to produce detailed images of the heart's structure and function, allowing healthcare providers to evaluate both the anatomy of the heart and how well it is working.

While "sonogram" often refers broadly to any ultrasound image and could technically include echocardiograms, it does not specifically denote the heart. A "cardiac CT scan" involves the use of X-rays to create detailed images of the heart and is distinctly different from an echocardiogram, which relies on ultrasound technology. Thus, it is important to use the precise term "cardiac ultrasound" or "echocardiogram" to convey the specific imaging technique used to assess heart functions and structures.
