Nano-Sized Ultrasound Contrast Agent: Salting-Out Method

Molecular Imaging, 2010
Tumor imaging by ultrasound is greatly enhanced by the use of ultrasound contrast agents (UCAs), stabilized, gas-filled bodies. They are generally less than 7 μm to pass freely through the capillary bed.

Sonophoresis Using Ultrasound Contrast Agents: Dependence on Concentration. [PDF]

PLoS ONE, 2016
Sonophoresis can increase skin permeability to various drugs in transdermal drug delivery. Cavitation is recognized as the predominant mechanism of sonophoresis.

CEUS LI-RADS: a pictorial review [PDF]

, 2020
Contrast-enhanced ultrasound (CEUS) greatly improved the diagnostic accuracy of US in the detection and characterization of focal liver lesions (FLLs), and it is suggested and often included in many international guidelines as an important diagnostic ...

Contrast enhanced ultrasound (CEUS) in breast tumors [PDF]

, 2013
Contrast-enhanced ultrasound or CEUS is a combination of the pharmacokinetics of contrast agents (or microbubbles-based ultrasound contrast agents), the signal processing of these agents and the contrast-specific imaging modality.

Self-demodulation effect on subharmonic response of ultrasound contrast agent [PDF]

, 2012
In this work the use of the self-demodulation (S-D) signal as a mean of microbubble excitation at the subharmonic (SH) frequency to enhance the SH emission of ultrasound contrast agent (UCA) is studied. SH emission from the UCA is of interest since it is

Transcranial Functional Ultrasound Imaging in Freely Moving Awake Mice and Anesthetized Young Rats without Contrast Agent

Ultrasound in Medicine and Biology, 2017
Functional ultrasound (fUS) imaging by ultrasensitive Doppler detection of blood volume was previously reported to measure adult rat brain activation and functional connectivity with unmatched spatiotemporal sampling (100 μm, 1 ms), but skull-induced ...

Evaluation of Microwave Ablation in 4T1 Breast Tumor by a Novel VEFGR2 Targeted Ultrasound Contrast Agents

Frontiers in Oncology, 2021
ObjectivesA novel ultrasound contrast agent (UCA) VEGFR2-targeting iron-doped silica (SiO2) hollow nanoparticles (VEGFR2-PEG-HSNs-Fe NPs) was prepared and applied in microwave ablation for breast cancer to investigate its value in the evaluation of ...

Ultrasound contrast agent delivered per os first diagnoses pharyngoesophageal tumour

Journal of the Belgian Society of Radiology, 2013
Oral administration of ultrasound contrast agents has been described very little so far in medical literature. These agents are mainly administered intravenously and, less commonly, intracavitarily.

Stable Thermally-Modulated Nanodroplet Ultrasound Contrast Agents

Nanomaterials, 2021
Liquid perfluorocarbon-based nanodroplets are stable enough to be used in extravascular imaging, but provide limited contrast enhancement due to their small size, incompressible core, and small acoustic impedance mismatch with biological fluids.

Role of contrast-enhanced ultrasound (CEUS) in paediatric practice: an EFSUMB position statement [PDF]

, 2016
The use of contrast-enhanced ultrasound (CEUS) in adults is well established in many different areas, with a number of current applications deemed off-label, but the use supported by clinical experience and evidence.
