Artery angiography, also known as arteriography or angiogram, is a medical imaging procedure used to visualize the arteries in the body. It is performed to diagnose and evaluate various conditions affecting the blood vessels, such as arterial blockages, narrowing (stenosis), aneurysms, and vascular malformations. The procedure is typically conducted by an interventional radiologist or an interventional cardiologist.
During artery angiography, a contrast dye is injected into the arteries, and X-ray images are taken as the dye flows through the blood vessels. The contrast dye is visible on X-rays, allowing the radiologist or cardiologist to see the structure and function of the arteries in real-time. This procedure is performed using fluoroscopy, a type of X-ray imaging that can capture moving images.
Artery angiography is a valuable tool in diagnosing and guiding the treatment of various vascular conditions. While it is generally safe, there are some risks associated with the procedure, such as allergic reactions to the contrast dye or injury to the blood vessels at the catheter insertion site. However, the benefits of the procedure often outweigh the risks, especially when it helps in making important medical decisions for the patient's care.
