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

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 of the Kidneys

2009
Several imaging techniques can be used for visualization of the kidneys dependent on the indication. Ultrasound (US), computerized tomography (CT), and magnetic resonance imaging (MRI) are most commonly used. US is a safe, relatively inexpensive, noninvasive, and widely available imaging method.

Practical Contrast Enhanced Liver Ultrasound

Radiologic Clinics of North America, 2022
Contrast-enhanced ultrasound (CEUS) is increasingly performed for focal liver lesion evaluation because of its high safety profile and ability to yield a definitive diagnosis in many patients, obviating multiphase CT or MRI. CEUS uses specific ultrasound contrast agents (UCAs) that are exceedingly safe, without the risk of renal or liver toxicity. UCAs

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 ...

Contrast-Enhanced Intraoperative Ultrasound of the Liver

Surgical Oncology Clinics of North America, 2022
Contrast-enhanced intraoperative ultrasound (CE-IOUS) is a relatively new but valuable tool that is increasingly used as an adjunct to computed tomography, MRI, and IOUS for patients undergoing liver surgery. CE-IOUS has an important role in 2 main settings: the discrimination of indeterminate lesions detected in cirrhotic livers by conventional IOUS ...

Contrast-Enhanced Ultrasound for the Prostate

2009
Imaging of the prostate can be performed using different imaging techniques and has several applications in the evaluation of benign and malignant prostate diseases. Many imaging techniques are used to detect and follow up abnormalities of the prostate such as prostatitis, abscesses, benign prostate hyperplasia, and prostate cancer, or to investigate ...

Contrast-enhanced ultrasound in urology

2018
In contrast-enhanced ultrasonography (CEUS), micrometer-sized, encapsulated, gas-filled microbubbles are employed to enhance the signals in ultrasound imaging. Since the microbubbles remain intravascular, CEUS is able to visualize perfusion of various tissues.

Contrast-enhanced ultrasound in pregnancy

Abdominal Radiology
There are complex problems related to diagnostic imaging of the pregnant patient Cross sectional imaging with computed tomography (CT) tends to be avoided to due to the risk radiation poses to the fetus and magnetic resonance imaging (MRI) may be limited due to avoidance of gadolinium contrast.While ultrasound (US) is the primary test for imaging in ...

Contrast-enhanced Ultrasound in Dermatomyositis- and Polymyositis

Journal of Neurology, 2006
To evaluate prospectively contrast-enhanced ultrasound (CEUS) in patients suspected of having dermatomyositis or polymyositis.In 35 patients (23 women, 12 men; mean age, 51 years+/-16 years) who were suspected of having dermatomyositis or polymyositis, perfusion in clinically affected skeletal muscles was quantified with contrast-enhanced intermittent ...
