Angiography

Angiography is a type of X-ray examination that creates detailed images of the arteries (blood vessels) and the blood flow inside them. These images are called angiograms.

Angiography involves injecting a special dye, called contrast medium, into the blood vessels. On the angiogram, this shows any abnormalities inside the blood vessels.

What is angiography used for?

Angiography is used to explore blood vessels in different parts of the body including:

• the brain,
• the heart,
• the kidneys,
• the eyes, and
• the extremities (arms and legs).

Types of angiography

Types of angiography include: 

• cerebral angiography (brain),
• coronary angiography (heart),
• pulmonary angiography (lungs),
• renal angiography (kidneys),
• lymphangiography (lymph vessels), and
• extremity angiography (arms or legs).
