SonoVue: Approved Indications Echocardiography … for use in patients with suspected or established cardiovascular disease to provide opacification of cardiac chambers and enhance left ventricular endocardial border delineation Microvascular enhacement …SonoVue® improves visualization of liver and breast lesion vascularity during Doppler Sonography, leading to more specific lesion characterization Macrovascular enhancement … increases the accuracy in detection or exclusion of abnormalities in cerebral arteries and extra-cranial carotid or peripheral arteries by improving the Doppler signal-to-noise ratio.
Ultrasound Contrast Agents : Unique Characteristics SonoVue is a pure blood pool agent that provides real-time information of the vasculature improves the diagnostic information from MACROcirculation has an unique role in providing information of the MICROcirculation (vessels diameter below 200 m) useful for tissue organ perfusion characterization
