myocardial contrast echocardiography

myocardial contrast echocardiography

An imaging tool for assessing myocardial microcirculation, which utilises inert-gas-filled microbubbles that remain entirely within the vascular space and possess an intravascular rheology similar to that of red blood cells. During IV infusion of the microbubbles and attainment of a steady state, the microbubbles are destroyed with high-energy ultrasound. The rate of microbubble replenishment within the ultrasound beam is measured, a value which corresponds to mean red cell velocity.
