Which term describes the radiographic imaging of blood vessels after contrast media is used?

The term that describes the radiographic imaging of blood vessels after contrast media is utilized is angiography. This procedure involves injecting a contrast agent into the bloodstream to enhance the visibility of the blood vessels during imaging. Angiography is crucial in diagnosing and evaluating various vascular conditions, such as blockages, abnormalities, or aneurysms, by allowing healthcare professionals to see the structure and function of blood vessels in detail.

The other terms mentioned pertain to different medical contexts. Abrasion refers to a wound or scrape on the skin surface, ostomy is a surgical procedure creating an opening from an area inside the body to the outside, typically for waste elimination, and artifact refers to distortions or anomalies in imaging that do not represent a real anatomical structure. These definitions place them outside the realm of vascular imaging, making angiography the appropriate term in this scenario.
