Angiography is used to visualize the inside of blood vessels, allowing doctors to diagnose and treat a variety of conditions.

Digital subtraction angiography (DSA) is commonly used to diagnose and treat atherosclerosis, as it provides real-time images of blood flow in arteries and veins.

Iodine is the primary contrast agent used in angiography, as it is relatively safe and provides good visualization of blood vessels.

Computed tomography (CT) is commonly used in conjunction with angiography to provide detailed anatomical information, as it can generate cross-sectional images of the body.

The primary risk associated with angiography is an allergic reaction to the contrast agent, which can range from mild to severe.

Cerebral angiography is commonly used to visualize blood flow in the brain, as it provides detailed images of the cerebral arteries and veins.

Pulmonary angiography is primarily indicated for diagnosing pulmonary embolism, which is a blockage of an artery in the lung.

Renal angiography is commonly used to evaluate blood flow in the kidneys, as it provides detailed images of the renal arteries and veins.

Coronary angiography is primarily indicated for diagnosing coronary artery disease, which is a narrowing of the arteries that supply blood to the heart.

Positron emission tomography (PET) is commonly used in conjunction with angiography to provide functional information about the heart, such as blood flow and metabolism.

Peripheral angiography is primarily indicated for diagnosing peripheral artery disease, which is a narrowing of the arteries in the legs or arms.

Abdominal angiography is commonly used to evaluate blood flow in the abdomen, as it provides detailed images of the abdominal arteries and veins.

Carotid angiography is primarily indicated for diagnosing carotid artery disease, which is a narrowing of the arteries that supply blood to the brain.

Magnetic resonance imaging (MRI) is commonly used in conjunction with angiography to provide detailed images of the heart, as it can generate cross-sectional images of the heart and its structures.

Mesenteric angiography is primarily indicated for diagnosing mesenteric ischemia, which is a condition in which the blood supply to the intestines is blocked.
