Contrast–enhanced ultrasonography in Crohn’s disease

La radiologia medica, 2006
The purpose of this study was to demonstrate the diagnostic efficacy of contrast-enhanced power Doppler (CEPD) after ultrasound (US) with colour power Doppler (CPD) in defining disease activity in patients with ileal Crohn's disease in the acute phase and during treatment follow-up.The study included 15 patients with ileal Crohn's disease, 12 of whom ...

Contrast-Enhanced Ultrasonography in Pancreas Transplantation

Transplantation, 2013
Pancreas transplantation remains a major surgery with potential complications that require reliable imaging despite impaired kidney function. Contrast-enhanced ultrasonography (CEUS) has been proven to be an indispensable tool in the evaluation of the native pancreas. Here, CEUS studies are extended to pancreas transplants for the first time.A total of

Contrast-Enhanced Ultrasonography in Hepatic Angiomyolipoma

Journal of Ultrasound in Medicine, 2005
Angiomyolipoma (AML) is a benign tumor of mesenchymal origin rarely found in the liver. It is composed of a variable mixture of 3 tissue components, including blood vessels, smooth muscle, and adipose cells.1 The imaging appearances of hepatic AML are quite variable and may overlap with those of other benign and malignant fat-containing hepatic lesions,

CONTRAST ENHANCED ULTRASONOGRAPHY OF THE DOG'S SPLEEN

2023
The present research aims to visualize and follow the arterial and venous blood vessels pattern and to detect the circulatory phases of the canine spleen. Six dogs included in the study were examined with conven-tional and contrast ultrasonography using SonoVue® (Bracco International B.V., Nederland) contrast agent. The main arterial and venous vessels

Intraarterial Contrast-Enhanced Ultrasonography Is the Final Goal of Intravenous Contrast-Enhanced Ultrasonography [PDF]

, 2003
Contrast-enhanced ultrasonography (US) falls into two broad categories: intraarterial and intravenous (Table 1–1). Intraarterial techniques use CO2 microbubbles as the contrast agent, whereas intravenous techniques use Levovist (300 mg/ml), the only contrast agent currently marketed in Japan.

Ultrasonography of the pancreas. 4. Contrast-enhanced imaging

Abdominal Imaging, 2006
The introduction of contrast-enhanced ultrasonography (CEUS) has lead to great developments in the diagnostic capabilities of ultrasound. Second generation contrast media, characterized by harmonic responses at low mechanical index of the ultrasound beam, have already proven usefulness in the study of the liver but other abdominal organs can take ...

Contrast-enhanced endoscopic ultrasonography in digestive diseases

Journal of Gastroenterology, 2012
Contrast-enhanced endoscopic ultrasonography (CE-EUS) was introduced in the early 1990s. The concept of the injection of carbon dioxide microbubbles into the hepatic artery as a contrast material (enhanced ultrasonography) led to "endoscopic ultrasonographic angiography". After the arrival of the first-generation contrast agent, high-frequency (12 MHz)

Neuroendocrine Tumors: Characterization with Contrast-Enhanced Ultrasonography

Ultraschall in der Medizin - European Journal of Ultrasound, 2008
The aim of this study was to characterize the ultrasonographic features of neuroendocrine tumors (NET) and their metastases with contrast-enhanced ultrasonography (CEUS) and to compare this to clinical data.During a period of 5 years, 82 patients with 83 histologically proven NET were prospectively examined using conventional US and pulse inversion US ...

Contrast enhancing agents in ultrasonography: Clinical applications

European Journal of Radiology, 1998
As ultrasound remains a poorly sensitive method, echocontrast agents make a real difference. At least 29 echocontrast agents are currently on trial worldwide; their chemical composition, mechanisms of action and possible clinical applications are different.
