Computerized intravenous arteriography: a technique for visualizing the peripheral vascular system.
A unique method of computerized fluoroscopic enhancement allows direct visualization of the entire vascular system by intravenous injection of standard contrast agents, thereby avoiding the need for arterial puncture or hospitalization. This technique has been used to satisfactorily visualize the intra- and extracranial carotid and vertebral arteries, the aortic arch and upper extremity vessels, the abdominal aorta and its branches, as well as lower extremity vasculature. Although the technique is still under development, occlusions, stenoses, ulcerated plaques, and aneurysms have been 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.
