regadenoson + optison

Regadenoson + Optison is a combination used in cardiac imaging procedures, particularly for myocardial perfusion and echocardiography. Regadenoson is a selective adenosine A2A receptor agonist that induces coronary vasodilation, increasing blood flow to the heart and helping identify areas of reduced perfusion due to coronary artery disease. Optison (perflutren protein-type A microspheres) is an ultrasound contrast agent that enhances the visualization of cardiac structures during echocardiography by opacifying the left ventricle and improving delineation of endocardial borders. This combination may be used in stress echocardiography protocols where regadenoson acts as a pharmacologic stress agent and Optison improves image quality[1][2][3][5][8].
