In-vivo quantitative ultrasound evaluation of carotid plaque

摘要

Carotid atherosclerotic plaque is a contributor to cerebrovascular disease. Noninvasive quantitative ultrasound (QUS) evaluations of plaque morphology are requisite for comprehensive risk assessments, as system and setting dependencies limit current grayscale analyses. Here, integrated backscatter (IB) and attenuation coefficient (AC) were calculated in-vivo and compared with pathology scores of excised plaque.
