Arteriography is best described as a radiograph that visualizes injected radiopaque dye in which structure?

Arteriography is best described as a radiograph that visualizes injected radiopaque dye in which structure?

• A. A joint capsule.
• B. The spinal canal.
• C. An artery.
• D. The liver vasculature.

Answer: (C)

Arteriography involves injecting radiopaque contrast into the arterial system and taking X-ray images to illuminate the arteries. The contrast fills the arterial lumen, making arteries stand out on the film and allowing visualization of their course, blockages, or abnormalities. The other scenarios describe imaging of different structures: a joint capsule requires arthrography, the spinal canal is seen with myelography, and while liver vasculature can be studied via hepatic arteriography, the general description of arteriography is specifically about visualizing arteries.
