Acoustic Sizing of an Ultrasound Contrast Agent [PDF]

Ultrasound in Medicine & Biology, 2010
Because the properties of ultrasound contrast agent populations after administration to patients are largely unknown, methods able to study them noninvasively are required. In this study, we acoustically performed a size distribution measurement of the ultrasound contrast agent Definity(®).

Ultrasound Contrast Agent Needle Priming: Impact on Sonographic Biopsy Needle Visibility in a Porcine Liver Model. [PDF]

Cardiovasc Intervent Radiol
Purpose:  The visibility of biopsy needles in contrast-specific imaging mode can be improved by priming them with an ultrasound contrast agent (previously demonstrated in a phantom model/ex vivo).

Ultrasound Contrast Agent Modeling: A Review [PDF]

Ultrasound in Medicine & Biology, 2020
Ultrasound is extensively used in medical imaging, being safe and inexpensive and operating in real time. Its scope of applications has been widely broadened by the use of ultrasound contrast agents (UCAs) in the form of microscopic bubbles coated by a biocompatible shell.

Ultrasound contrast agents

Endoscopic Ultrasound, 2016
Endoscopic ultrasound (EUS) plays an important role in imaging of the mediastinum and abdominal organs. Since the introduction of US contrast agents (UCA) for transabdominal US, attempts have been made to apply contrast-enhanced US techniques also to EUS. Since 2003, specific contrast-enhanced imaging was possible using EUS. Important studies have been

Effects of ultrasound and ultrasound contrast agent on vascular tissue

Cardiovascular Ultrasound, 2012
Background Ultrasound (US) imaging can be enhanced using gas-filled microbubble contrast agents. Strong echo signals are induced at the tissue-gas interface following microbubble collapse.

Renal perfusion in scleroderma patients assessed by microbubble-based contrast-enhanced ultrasound [PDF]

, 2012
OBJECTIVES: Renal damage is common in scleroderma. It can occur acutely or chronically. Renal reserve might already be impaired before it can be detected by laboratory findings.

Acoustically-Stimulated Nanobubbles: Opportunities in Medical Ultrasound Imaging and Therapy

Frontiers in Physics, 2021
Medical ultrasound is one of the most widely used imaging modalities worldwide. Microbubbles, typically ~1–8 μm in diameter, are ultrasound contrast agents confined to the vasculature due to their size.
