Which term denotes the process of recording pictures of the heart and blood vessels?

• A. Electrocardiography
• B. Radiography
• C. Echocardiography
• D. Angiocardiography

Answer: (D)

Recording pictures of the heart and blood vessels is angiocardiography. The term combines angio- (vessels) and cardio- (heart) with -graphy (recording/images), and it typically uses a contrast dye with X-ray imaging to visualize both the heart chambers and the vascular structures. This distinguishes it from electrocardiography, which only records the heart’s electrical activity; radiography, a general X-ray technique; and echocardiography, which uses ultrasound to image heart structure and motion rather than the vessels with contrast.
