Microangiography (/ˌmaɪkroʊˌændʒiˈɒɡrəfi/ MY-kroh-AN-jee-OG-rə-fee) [1] is a type of angiography that consists of the radiography of small blood or lymphatic vessels of an organ. While most other types of angiography cannot produce images of vessels smaller than 200 µm in diameter, microangiography does just that.[2] A microangiographic image is the result of injection of a contrast medium into either the blood or the lymphatic system and, then, enlargement of the resulting radiograph. Thus, an image is obtained in which there is contrast between vessel and surrounding tissue.
