Distinguishing characteristics of erythrocyte-rich and platelet-rich thrombus by intravascular ultrasound catheter system

Background Acute coronary syndromes are associated with platelet-rich, white thrombi (WT) and erythrocyte-rich, red thrombi (RT), but their ultrasonic characteristics are not well defined. To determine whether intravascular ultrasound (IVUS) could be used to detect specific characteristics of WT and RT, two experiments were performed.
