Ultrasound contrast agents are gas-filled micro-bubbles which are injected into the blood stream. Micro-bubbles will give increased backscatter signal due to the large acoustic impedance mismatch between the gas-filled bubble and surrounding tissue Micro-bubble suspension is injected intravenously into the systemic circulation in a small bolus. The micro-bubbles...Continue reading »
