Molecular Ultrasound Imaging [PDF]

Nanomaterials, 2020
Contrast-enhanced ultrasound (CEUS) imaging is a valuable tool for preclinical and clinical diagnostics. The most frequently used ultrasound contrast agents are microbubbles. Besides them, novel nano-sized materials are under investigation, which are briefly discussed in this chapter.

Ultrasound Tongue Imaging [PDF]

, 2021
Ultrasound has been used as a diagnostic medical tool since 1956. In 1969 Kelsey, Minifie and Hixon proposed using ultrasound to image the tongue (Ultrasound Tongue Imaging: UTI) as a safer alternative to x-ray imaging for viewing the articulators in both typical and disordered speech production.

Predictive Value of the Transthoracic Echocardiography Index for Acute Kidney Injury after Cardiac Valve Surgery

Journal of Cardiovascular Development and Disease, 2022
Background: We aimed to demonstrate whether the preoperative transthoracic echocardiography index (TTEI) could improve the predictive value of clinical parameters for cardiac valve surgery-associated acute kidney injury (CVS−AKI). Methods: A total of 213

Amplified antitumor efficacy by a targeted drug retention and chemosensitization strategy-based “combo” nanoagent together with PD-L1 blockade in reversing multidrug resistance

Journal of Nanobiotechnology, 2021
Background Recent studies have demonstrated that multidrug resistance (MDR) is a critical factor in the low efficacy of cancer chemotherapy. The main mechanism of MDR arises from the overexpression of P-glycoprotein (P-gp), which actively enhances drug ...

Sparsity driven ultrasound imaging [PDF]

The Journal of the Acoustical Society of America, 2012
An image formation framework for ultrasound imaging from synthetic transducer arrays based on sparsity-driven regularization functionals using single-frequency Fourier domain data is proposed. The framework involves the use of a physics-based forward model of the ultrasound observation process, the formulation of image formation as the solution of an ...
