What is the radiographic visualization of blood vessels after the injection of a radiopaque substance called?

• A. Angiography
• B. Angioplasty
• C. Venography
• D. Angiogram

Answer: (D)

The imaging you get after injecting a radiopaque contrast to visualize blood vessels is called an angiogram. The study that produces this visualization is angiography, but the actual image you see is the angiogram. Angioplasty is a procedure to widen narrowed vessels, not an image. Venography specifically images veins, not the general arterial and venous network, and while angiography refers to the imaging process, the single radiographic image produced is the angiogram.
