Angiography is a medical imaging technique used to visualize the blood vessels, typically within the heart, brain, or extremities. The procedure involves injecting a contrast dye into the bloodstream and using X-rays or other imaging modalities to capture detailed images of the blood vessels. This technique is commonly used to diagnose and assess the condition of blood vessels, detect blockages, and evaluate the effectiveness of treatments such as angioplasty or stent placement.

Angiography can be performed using various imaging methods, including:

1. X-ray angiography: This traditional method uses X-rays to visualize the blood vessels after contrast dye injection. It is often used to assess coronary artery disease.

2. Computed tomography angiography (CTA): This non-invasive technique combines X-ray imaging with computer processing to create detailed 3D images of the blood vessels. CTA is useful for evaluating both coronary and peripheral arteries.

3. Magnetic resonance angiography (MRA): This technique uses magnetic resonance imaging (MRI) to visualize blood vessels without the need for contrast dye. MRA is particularly useful for evaluating the brain's blood vessels and is generally considered safer for patients with kidney problems.

Angiography is an essential tool in the diagnosis and management of vascular diseases, helping healthcare professionals to plan and monitor treatments effectively. However, it also carries risks, including allergic reactions to contrast dye and radiation exposure, which must be carefully considered and managed.
