2024年6月28日 · Contrast-enhanced ultrasound (CEUS) involves the administration of intravenous contrast agents consisting of microbubbles /nanobubbles of gas. Contrast-enhanced voiding ultrasonography is a special CEUS exam for which the diluted microbubbles are given intravesically via a urinary catheter.

Contrast-enhanced ultrasound produces enhanced images of tissue compared to B-mode ultrasound which aids in determining tissue pathology. Its ability to determine tissue perfusion helps determine changes in vascularization in tissue parenchyma secondary to pathological processes or in the pathological lesion in response to treatment.

Contrast-enhanced ultrasound imaging is a recently approved technique in the United States that uses a specific contrast agent, namely, microbubbles, consisting mainly of a gas core and a stabilized biological shell. These compounds allow for …

Contrast-enhanced ultrasound uses an intravenous agent that contains microbubbles. The contrast helps providers see the flow of blood through your organs and blood vessels. It can help detect a variety of diseases and conditions.

Amplitude modulation (AM) suppresses tissue signals and detects microbubble signals in contrast-enhanced ultrasound (CEUS) and is often implemented with checkerboard apertures. However, possible crosstalk between transmitting and non-transmitting ...

2005年1月1日 · A prospective study that assessed the diagnostic accuracy of transhepatic circulatory time with an ultrasound contrast agent demonstrated that the hepatic artery to hepatic vein and portal vein to hepatic vein interval times were significantly shorter in the cirrhosis group Contrast-enhanced Ultrasound 115J Med Ultrasound 2005 • Vol 13 • No ...

Contrast-enhanced ultrasound (CEUS) uses an intravascular contrast agent to enhance blood flow signals and assess microcirculation in different parts of the human body.

2023年10月24日 · Ultrasound contrast has no renal toxicity or clearance; therefore, CEUS may be used at any level of renal function. CEUS is often safe for patients with contraindications to computed tomography (CT) or magnetic resonance imaging (MRI), including allergies to iodinated and gadolinium-based contrast material, claustrophobia, or immobility.

2024年10月1日 · Contrast-enhanced ultrasound (CEUS) is a medical imaging technique that offers multiple advantages over other modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). These advantages include portability, no ionising radiation and no renal toxicity, with the great advantage of real-time imaging.

CEUS is a promising imaging technique for point-of-care applications in pediatric and adult patients and can be applied for patients with allergy to CT contrast medium or with impaired renal function. More high-quality CEUS research focusing on accuracy, patient safety, health care costs, and throug …
