Angiography is a diagnostic procedure that involves taking X-ray images of blood vessels after injecting a contrast agent or dye. It is used to examine the blood vessels throughout the body, including the heart, brain, lungs, kidneys, and legs.
Angiography is typically performed to diagnose and evaluate conditions that affect the blood vessels, such as blockages, narrowing, or malformations. It can help doctors identify the location and extent of the problem, as well as determine the most appropriate treatment options.
For example, angiography of the heart, also known as coronary angiography, is used to diagnose coronary artery disease and blockages in the heart’s blood vessels. Angiography of the brain, also known as cerebral angiography, can help diagnose conditions such as aneurysms, stroke, and arteriovenous malformations.
In addition to diagnosing conditions, angiography can also be used to guide and monitor certain treatments, such as the placement of stents or catheters to open up blocked or narrowed blood vessels.
While angiography is generally considered safe, it does carry some risks, such as allergic reactions to the contrast dye or bleeding at the site of injection. Therefore, it is important to discuss the potential benefits and risks of angiography with your healthcare provider before undergoing the procedure.
