Summary
Contrast enhancement of computerized tomography is usually performed by means of intravenous injection of iodinated contrast materials. The authors have utilized a technique of direct arterial infusion of iodinated contrast material supplying intracranial arteries during computerized axial tomography. A representative case is presented with comparison scans which were obtained without contrast enhancement and with conventional intravenous infusion of contrast. Marked improvement of the enhancement was clearly demonstrated in this case, with abnormalities readily defined that were not seen with the conventional intravenous enhancement procedure.
