Paper Abstract

Digital subtraction videoangiography has been proven to be suitable for imaging the left ventricle and other cardiac chambers.l,2 The high contrast sensitivity and good cancellation of structural background enable this imaging technique to be used with intra-venous injections, which result in complete mixing of contrast medium with blood in the left ventricle.3 The digital nature of the image processor used in subtraction video-angiography enables convenient data collection and analysis. For these reasons, digital videoangiography is well suited to videodensitometric calculation of physiological quantities such as left ventricular ejection fraction.
