Abstract

A combined preparation comprising: i) an ultrasound contrast agent capable of accumulation in tissue microvasculature; and ii) a pharamacologically effective amount of a vasodilator drug may be used in perfusion imaging, especially of the myocardium. The contrast agent accumulates in tissue in concentrations related to the regional rate of tissue perfusion, and the vasodilator drug enhances distinction between normally perfused and underperfused tissue.
