Characterization of Focal Liver Masses: A Multicenter Comparison of Contrast‐Enhanced Ultrasound, Computed Tomography, and Magnetic Resonance Imaging

Journal of ultrasound in medicine, 2021
To demonstrate the usefulness of contrast‐enhanced ultrasound (CEUS) for the evaluation of focal liver masses via a direct comparison to standard ultrasound and computed tomography/magnetic resonance imaging (CT/MRI).

Contrast-Enhanced Ultrasound

Magnetic Resonance Imaging Clinics of North America, 2017
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 the visualization of small vascular beds and improve characterization of anatomic structures and lesions.

Value of Qualitative and Quantitative Contrast‐Enhanced Ultrasound Analysis in Preoperative Diagnosis of Cervical Lymph Node Metastasis From Papillary Thyroid Carcinoma

Journal of ultrasound in medicine, 2020
To investigate the qualitative and quantitative characteristics of contrast‐enhanced ultrasound (CEUS) in assessing cervical lymph node metastasis from papillary thyroid carcinoma (PTC) and to evaluate its value in the preoperative diagnosis of cervical ...

Contrast-Enhanced Ultrasound (CEUS)

2021
Contrast-enhanced ultrasound (CEUS) imaging is a widely used medical imaging technique combining ultrasound and ultrasound contrast agents (UCAs) for clinical decision-making. UCAs are gas microbubbles coated with a biocompatible shell; they stay intravascular and act as resonant scatterers producing echoes with characteristic harmonics that can be ...

Contrast-Enhanced Ultrasound Ventriculography

Operative Neurosurgery, 2012
During external ventricular drainage (EVD) weaning, cranial computed tomography (cCT) is necessary to evaluate ventricle width. Because intrahospital transfer of critically ill patients is associated with higher mortality, bedside techniques are necessary to evaluate ventricle width.

Contrast-Enhanced Ultrasound Algorithms (CEUS-LIRADS/ESCULAP) for the Noninvasive Diagnosis of Hepatocellular Carcinoma – A Prospective Multicenter DEGUM Study

Ultraschall in der Medizin - European Journal of Ultrasound, 2020
Background This prospective multicenter study funded by the DEGUM assesses the diagnostic accuracy of standardized contrast-enhanced ultrasound (CEUS) for the noninvasive diagnosis of hepatocellular carcinoma (HCC) in high-risk patients. Methods Patients

Contrast-Enhanced Ultrasound (CEUS) in Nephrology

2021
Contrast-enhanced ultrasound (CEUS) represents one of the most interesting and promising examples of imaging application in clinical practice. Ultrasound contrast media are defined as “blood pool” agents because they remain confined into blood vessels without reaching the excretory tract.

Contrast-enhanced ultrasound in coxitis

Joint Bone Spine, 2016
Hip involvement is common in rheumatological diseases but can be difficult to diagnose, especially in absence of MRI. B-mode ultrasound (US) detects joint capsule distention while distinguishing effusion from proliferative synovial tissue is strenuous since both appear hypoechoic. Power Doppler ultrasound (PDUS) often fails to detect vascularisation in

Preoperative Prediction of Cervical Lymph Node Metastasis in Papillary Thyroid Carcinoma via Conventional and Contrast‐Enhanced Ultrasound

Journal of ultrasound in medicine, 2020
To investigate the independent risk factors for cervical lymph node metastasis (CLNM) in patients with papillary thyroid carcinoma (PTC) and establish a prediction model via conventional ultrasound (US) and contrast‐enhanced ultrasound (CEUS).

Endoscopic Ultrasound: Contrast Enhancement

Gastrointestinal Endoscopy Clinics of North America, 2012
The development of ultrasound contrast agents has allowed for the evaluation of vascularity in digestive organs by contrast-enhanced endoscopic ultrasonography (EUS). Contrast-enhanced Doppler EUS and contrast-enhanced harmonic EUS (CH-EUS) have improved characterization of pancreatic tumors, lymph nodes, and gastrointestinal submucosal tumors and ...
