(phlebography) n. imaging of the anatomy of veins in a particular region of the body. Traditionally a radiopaque contrast medium is injected into a vein and X-ray photographs (venograms) taken as the medium flows towards the heart. Damage, obstruction, or abnormal communication with other vessels can be demonstrated. A common usage is in demonstrating deep vein thrombosis in the legs. Increasingly ultrasound is now used, both with colour Doppler (see Doppler ultrasound) and compression venography. See also angiography.
