    Thrombi developing within the origin of the internal carotid artery may be demonstrated by a slow trickle injection of highly concentrated contrast medium, which lingers in pools around the thrombus on the dependent wall of the vessel. With this technique thrombi have been detected which could not be visualized on conventional arteriography because they were obscured by the density of the vascular shadow produced by the forceful injection usually employed in carotid angiography. In addition, trickle arteriography is useful for assessing the position and extent of atheromatous plaques and the contrast stasis associated with them.
