What procedure involves inserting a catheter into a blood vessel and using contrast material for imaging?

The procedure that involves inserting a catheter into a blood vessel and using contrast material for imaging is known as an arteriogram. This imaging technique specifically targets arteries and allows healthcare professionals to visualize the interior of blood vessels. During the procedure, a catheter is inserted into a blood vessel, often in the groin or arm, and contrast dye is injected. This dye then highlights the arteries on x-ray images, enabling the identification of blockages, abnormalities, or other vascular conditions.

The focus on arteries is what distinguishes arteriograms from other imaging procedures. For instance, while a venogram also involves the use of a catheter and contrast material, it is specifically aimed at visualizing veins rather than arteries. Electrocardiography and ultrasound do not use catheter insertion or contrast materials; electrocardiography records electrical activity of the heart, while ultrasound utilizes sound waves for imaging. Thus, the distinction of targeting arteries with the use of injected contrast material is precisely what makes arteriogram the correct answer in this context.
