A molecular intravascular ultrasound contrast agent allows detection of activated platelets on the surface of symptomatic human plaques

LIBS-SL-MB allows ex vivo IVUS imaging of even small numbers of activated platelets on the surface of human carotid endarterectomy specimens. This diagnostic approach could deliver valuable additional information for risk stratification of atherosclerotic plaques, especially since we apply a clinically well-established IVUS imaging system.
