An Alternative Approach to Spectrum-Based Atherosclerotic Plaque Characterization Techniques Using Intravascular Ultrasound (IVUS) Backscattered Signals
In this paper, the discrete wavelet packet frames are used to delineate the atherosclerotic plaque components using intravascular ultrasound (IVUS) backscattered signals. The frames are classified in an unsupervised fashion deploying K-means clustering technique and the generated prognosis histology (PH) images are quantified using relative histology images. While existing tissue characterizati...
متن کاملRenal artery atherosclerotic plaque ruptures visualised with intravascular ultrasound.
Renal angiography frequently yields indeterminate results (particularly in aneurysms), that in coronaries were found to be plaque rupture sites. In this setting, use of intravascular ultrasound (IVUS) allows unique insights into actual lesion anatomy. We present three cases with striking in-vivo IVUS visualisation of renal artery atherosclerotic plaque rupture. Panels A, B, and C show three dis...
متن کاملUltrasound Tissue Characterization of Vulnerable Atherosclerotic Plaque
A thrombotic occlusion of the vessel fed by ruptured coronary atherosclerotic plaque may result in unstable angina, myocardial infarction or death, whereas embolization from a plaque in carotid arteries may result in transient ischemic attack or stroke. The atherosclerotic plaque prone to such clinical events is termed high-risk or vulnerable plaque, and its identification in humans before it b...
متن کاملStudy of atheromatous plaque using intravascular ultrasound.
T he increasing incidence of metabolic risk factors in the modern world makes it reasonable to predict that atheromatous cardiovascular disease will become the primary cause of death worldwide by 2020. An understanding of the factors that influence the natural history of atherosclerosis and its complications is essential for the future development of strategies for prevention and therapeutic in...
متن کاملGlobal characterization of coronary plaque rupture phenotype using three-vessel intravascular ultrasound radiofrequency data analysis.
AIMS To compare the global characteristics of patients with and without evidence of plaque rupture (PR) in their coronary tree and to evaluate the phenotype of ruptured plaques using intravascular ultrasound (IVUS) radiofrequency data analysis (IVUS-VH). METHODS AND RESULTS Forty patients underwent three-vessel IVUS-VH interrogation. Twenty-eight PRs were diagnosed in 26 vessels (25.7% of the...
