Ultrasound-Based Carotid Elastography for Detection of Vulnerable Atherosclerotic Plaques Validated by Magnetic Resonance Imaging
Chengwu Huang,Xiaochang Pan,Qiong He,Manwei Huang,Lingyun Huang,Xihai Zhao,Chun Yuan,Jing Bai,Jianwen Luo +8 more
TL;DR: The in vivo capability of carotid elastography to detect vulnerable plaques, validated by magnetic resonance imaging, was proven, revealing the potential of caro-elastography as an important tool in atherosclerosis assessment and stroke prevention.

Carotid Artery Plaque Vulnerability Assessment Using Noninvasive Ultrasound Elastography: Validation With MRI.
Marie-Hélène Roy Cardinal,Maarten H. G. Heusinkveld,Maarten H. G. Heusinkveld,Zhao Qin,Richard G.P. Lopata,Cyrille Naim,Gilles Soulez,Guy Cloutier +7 more
TL;DR: The imaging parameters cumulated axial translation and the ratio of cumulation axial strain to cumulatedAxial translation, as computed using NIVE, were able to discriminate vulnerable carotid artery plaques characterized by MRI from nonvulnerable carotids.

Imaging of high-risk carotid plaques: ultrasound.
Rafael S. Cires-Drouet,Mahvash Mozafarian,Amir Ali,Siddhartha Sikdar,Brajesh K. Lal,Brajesh K. Lal +5 more
TL;DR: New research into the mechanisms for plaque rupture and atheroembolic stroke indicates that the degree of narrowing is an imperfect predictor of stroke risk, and that other factors, such as plaque composition and remodeling and biomechanical forces acting on the plaque can play a role.

Non-invasive Identification of Vulnerable Atherosclerotic Plaques Using Texture Analysis in Ultrasound Carotid Elastography: An In Vivo Feasibility Study Validated by Magnetic Resonance Imaging.
TL;DR: The results indicate that the use of texture analysis in plaque classification is feasible and that larger local deformations and higher level of complexity in deformation patterns (associated with the elastic or stiffness heterogeneity of plaque tissues) are more likely to occur in vulnerable plaques.

Lessons From Sudden Coronary Death A Comprehensive Morphological Classification Scheme for Atherosclerotic Lesions
TL;DR: This review will reconsider the current paradigm for understanding the critical, final steps in the progression of atherosclerotic lesions, and devise a simpler classification scheme that is consistent with the AHA categories but is easier to use, able to deal with a wide array of morphological variations, and not overly burdened by mechanistic implications.

Ultrasound elastography: Principles and techniques
TL;DR: The principles of elastographic techniques are introduced and a technical summary for the main elastography techniques are given: from quasi-static methods that require a static compression of the tissue to dynamic methods that uses the propagation of mechanical waves in the body.

B-spline snakes: a flexible tool for parametric contour detection
P. Brigger,J. Hoeg,Michael Unser +2 more
TL;DR: A novel formulation for B-spline snakes is presented that can be used as a tool for fast and intuitive contour outlining, and the intrinsic scale of the spline model is adjusted a priori, leading to a reduction of the number of parameters to be optimized and eliminates the need for internal energies.
