COMMENTS

An angiogram is created by injecting an iodine solution into the bloodstream of the pulmonary artery through a catheter. The pulmonary arteries are first opacified, then as the iodine solution collects in the pulmonary venous structures (now, of course containing oxygenated blood having passed through the lung alveoli), the anatomy of these veins is revealed. The pulmonary veins lie somewhat more horizontal than the arteries and coalesce centrally toward the left atrium.
