Digital chest radiography.
Experimental and early clinical experience in intravenous angiocardiography using digital image processing has shown that the method is useful to defect left-to-right shunts and to calculate left ventricular volume and ejection fraction as well as to evaluate wall motion abnormalities. The resolution of the images is higher than of those obtained with other noninvasive methods such as echocardiography and scintigraphy.
