Abstract
• A unique method of computerized image enhancement makes it possible to visualize the arteriovascular system by intravenous (IV) injection of small doses of standard contrast agent. This technique has been used to study the intracranial and extracranial circulation of more than 100 patients. Occlusion, stenosis, aneurysmal change, plaquing, and ulceration can be identified by computerized IV arteriography. Failures (less than 10%) result from inadequate venous access, extravasation of dye, or patient motion. This technique avoids the need for arterial puncture, thereby significantly reducing the risks of arteriography. The major risk of IV arteriography is contrast medium reaction. There is a close correlation between IV and standard arteriographic images. Intravenous arteriography does not require hospitalization, is suited for repetitive testing, and has promise as a method of diagnostic screening for stroke prevention.
