Transvenous xeroarteriography: noninvasive method for demonstrating peripheral arteries.

Xeroradiography allows visualization of peripheral arteries after intravenous injection of relatively low quantities of contrast medium. By means of a special changer, several exposures are chosen according to standardized programs. Determination of the arrival time of the contrast medium after its passage through the heart and the lungs is not necessary. The method has proved effective in demonstration of localized vascular lesions and evaluation of postoperative status and soft tissue tumors. Transvenous examinations of 237 patients are reported.
