Description

Experimental and clinical studies on the distribution of the contrast agents in vein indicate that the gravity plays a main role. As the hyperbaric contrast agents preferentially flow beneath the blood, posterior walls of the veins are clearly delineated contray to the poor visualization of the anterior walls in supine position. To avoid this disadvantage, the authors stressed that additional to supine, prone or upright lateral and anteroposterior projection were advisable.
