Breast tumor classification using axial shear strain elastography: a feasibility study
TL;DR: A feasibility study on the utility of the axial-shear strain elastograms in the classification of in vivo breast tumor as being benign or malignant suggests that for the discriminant feature value of 0.46, the number of unnecessary biopsies could be reduced by 56.3% without compromising on sensitivity and on negative predictive value (NPV).
Journal ArticleDOI

TL;DR: It is shown that PX-478 prevents postradiation HIF-1 signaling and abrogates downstream stromal adaptation in C6 and HN5 reporter xenografts as measured by serial ultrasound, vascular magnetic resonance imaging, and hypoxia response element–specific micro–positron emission tomography imaging.
Journal ArticleDOI
Visualization of bonding at an inclusion boundary using axial-shear strain elastography: a feasibility study.
Arun Thitaikumar,Thomas A. Krouskop,Thomas A. Krouskop,Brian S. Garra,Jonathan Ophir,Jonathan Ophir +5 more
TL;DR: The overall hypothesis of this work is that the pattern of axial-shear strain distribution around the inclusion/background interface is completely determined by the bonding at the interface after normalization for inclusion size and applied strain levels, and that it is feasible to extract certain features from the axial, shear strain elastograms to quantify this pattern.
Journal ArticleDOI
Effect of lesion boundary conditions on axial strain elastograms: a parametric study.
TL;DR: A parametric study using finite element modeling (FEM) to investigate the validity of the analytical expression relating the strain contrast to the modulus contrast, when the state of bonding at the inclusion/background interface spans a large dynamic range suggests that estimated modulus Contrast is sensitive to the region-of-interest within the inclusion that is considered in the computation of the strain Contrast.
