The technique transformation image the sound barrier in echocardiographic
Parasternal view with normal aorta after intravenous administration of ultrasound contrast agent. An electrocardiogram is provided for this time. Upper: Systolic, in which contrast is clearly defined in the arch of the aorta. Below: The diastolic of the same cardiac cycle, in less contrast, is shown. In real-time imaging, note the phase appearance and disappearance of contrast in the aorta. During diastole, when there is little flow in the aorta, there is plenty of time for ultrasound interaction with the contrast material and it is gradually destroyed.
