Mechanism of Action

—

12.1 Mechanism of Action The OPTISON microspheres create an echogenic contrast effect in the blood. The acoustic impedance of the OPTISON microspheres is much lower than that of the blood. Therefore, impinging ultrasound waves are scattered and reflected at the microsphere-blood interface and ultimately may be visualized in the ultrasound image. At the frequencies used in adult echocardiography (2 MHz to 5 MHz), the microspheres resonate which further increases the extent of ultrasound scattering and reflection.
