Study Summary
This is a pilot clinical trial to assess the ability of a new ultrasound-based imaging method, Acoustic Radiation Force Impulse (ARFI) ultrasound, to describe the composition and structure of atherosclerotic plaques. The hypothesis being tested is that in vivo, transcutaneous ARFI ultrasound delineates plaque composition and structure in human carotid arteries.
Primary Outcome
Statistical area under the curve (AUC) scores will be calculated using trained readers and spatially matched pathologist's interpretation of histochemical data. AUC scores will be determined for each of the four ARFI beam sequences implemented in this study with respect to characterizing calcium deposits, lipid/necrotic core, fibrous caps, collagen deposits, elastin deposits, disrupted internal elastic lamina, and thrombus.
