Which term denotes imaging of the heart and its vessels?

• A. Angiography
• B. Cardiology
• C. Angiocardiography
• D. Electrocardiography

Answer: (C)

Understanding how these terms are built helps you see why angiocardiography is the right choice. The parts angio-, cardio-, and -graphy each add meaning: angio- means vessel, cardio- means heart, and -graphy indicates imaging or recording. Put together, angiocardiography specifically refers to imaging of the heart and its vessels.

Angiography, while related, focuses on imaging blood vessels in general, not necessarily the heart itself. Electrocardiography records the heart’s electrical activity, not its structure or vessels. Cardiology is the medical specialty that studies the heart, not a type of imaging study. So angiocardiography uniquely conveys imaging of both the heart and its vascular structures.
