COMPUTERIZED INTRAVENOUS ARTERIOGRAPHY - A TECHNIQUE FOR VISUALIZING THE PERIPHERAL VASCULAR SYSTEM

Abstract

A unique method of computerized fluoroscopic enhancement allows direct visualization of the entire vascular system by i.v. injection of standard contrast agents, avoiding the need for arterial puncture or hospitalization. This technique was used to visualize the intra- and extracranial carotid and vertebral arteries, the aortic arch and upper extremity vessels, the abdominal aorta and its branches and lower extremity vasculature in patients. Although the technique is still under development, occlusions, stenoses, ulcerated plaques and aneurysms were visualized. Qualitative evaluation of these studies indicates a promising correlation with standard arteriography. This technique has great promise as a method of diagnostic screening in the management of peripheral vascular disease.
