摘要
Myocardial perfusion is assessed quantitatively by an ultrasonic echocardiographic procedure in which: the myocardium is ultrasonically imaged; an ultrasonic contrast agent consisting of a suspension of pressure-stable, water-insoluble gas-containing microspheres sized to pass through the pulmonary capillaries is injected intravenously; imaging is continued through the first transit of the microspheres through the myocardium; the videodensity versus time relationship is determined from the images; and blood flow through the myocardium is calculated from that relationship.
