Electronic Staining: Elasticity Imaging of Atheroma with Transcutaneous Ultrasound
نویسندگان
چکیده
This paper describes a noninvasive method for evaluating regional elasticity in atheroma in which a novel method is applied to measure minute changes in thickness of each of the multiple layers of the arterial wall during one heartbeat. By comparing the pathological findings with the elasticity distribution, statistic parameters for lipid and a mixture of smooth muscle and collagen fiber can be determined. By applying the method to the common carotid arteries (CCAs), thin collagen fiber was clarified and soft inclusion of lipid in plaque was detected. This method offers potential for detection of plaque vulnerability in a clinical setting.

متن کاملOn the potential of a new IVUS elasticity modulus imaging approach for detecting vulnerable atherosclerotic coronary plaques: in vitro vessel phantom study.
Peak cap stress amplitude is recognized as a good indicator of vulnerable plaque (VP) rupture. However, such stress evaluation strongly relies on a precise, but still lacking, knowledge of the mechanical properties exhibited by the plaque components. As a first response to this limitation, our group recently developed, in a previous theoretical study, an original approach, called iMOD (imaging ...
