Journal ArticleDOI
A heterogeneous nonlinear attenuating full- wave model of ultrasound
TL;DR: A mechanism of harmonic image quality improvement by showing that the harmonic point spread function is less sensitive to reverberation clutter is demonstrated, and a numerical solution of the relaxation attenuation laws that allows modeling of arbitrary frequency dependent attenuation is presented.
Journal ArticleDOI
Derivation and analysis of viscoelastic properties in human liver: impact of frequency on fibrosis and steatosis staging
Kathryn R. Nightingale,Ned C. Rouze,Stephen J. Rosenzweig,Michael H. Wang,Manal F. Abdelmalek,Cynthia D. Guy,Mark L. Palmeri +6 more
TL;DR: A robust, model-based algorithm and a linear dispersion model are described and used to perform shear wave dispersion analysis in traditionally difficult-to-image subjects.
Journal ArticleDOI
Tumor Elastography and Its Association with Collagen and the Tumor Microenvironment.
Johannes Riegler,Yassin Labyed,Stephen J. Rosenzweig,Vincent Javinal,Alessandra Castiglioni,Claudia X. Dominguez,Jason E. Long,Qingling Li,Wendy Sandoval,Melissa R. Junttila,Shannon J. Turley,Jill Schartner,Richard A.D. Carano +12 more
TL;DR: US elastography can be used as a potential biomarker to assess changes in the tumor microenvironment, particularly changes affecting the ECM, which may affect treatment efficacy and contribute to tissue stiffness.
Journal ArticleDOI
Acoustic Radiation Force Impulse Imaging of Human Prostates: Initial In Vivo Demonstration
Liang Zhai,Thomas J. Polascik,Wen-Chi Foo,Stephen J. Rosenzweig,Mark L. Palmeri,John F. Madden,Kathryn R. Nightingale +6 more
TL;DR: Acoustic radiation force impulse imaging holds promise for guidance of targeted prostate needle biopsy and focal therapy, as well as aiding assessment of changes during watchful waiting/active surveillance.
Journal ArticleDOI
Contrast-enhanced in vivo magnetic resonance microscopy of the mouse brain enabled by noninvasive opening of the blood-brain barrier with ultrasound.
Gabriel P. Howles,Kristin F. Bing,Yi Qi,Stephen J. Rosenzweig,Kathryn R. Nightingale,G. Allan Johnson +5 more
TL;DR: The BBB was opened in mice, using unfocused ultrasound combined with an injection of microbubbles, which opens the BBB throughout the brain and enables the administration of both existing anatomic contrast agents and the newer molecular/sensing contrast agents.
