Ultrasound Despeckling for Contrast Enhancement [PDF]

open access: yesIEEE Transactions on Image Processing, 2010
Images produced by ultrasound systems are adversely hampered by a stochastic process known as speckle. A despeckling method based upon removing outlier is proposed. The method is developed to contrast enhance B-mode ultrasound images. The contrast enhancement is with respect to decreasing pixel variations in homogeneous regions while maintaining or ...

Contrast‐enhanced endoscopic ultrasound [PDF]

open access: yesDigestive Endoscopy, 2013
Compared to other imaging modalities, endoscopic ultrasound (EUS) has limitations in terms of image enhancement. However, with the availability of contrast agents in ultrasonography, EUS has evolved. Contrast‐enhanced Doppler EUS (CD‐EUS) enhances Doppler signals from vessels and is useful for characterizing lesions detected by EUS.

Contrast-enhanced ultrasound of the pancreas [PDF]

open access: yesWorld Journal of Radiology, 2010
The introduction of contrast-enhanced ultrasonography (CEUS) has led to major improvements in the diagnostic capabilities of ultrasound (US). The innovative use of CEUS for study of the pancreas has created the need for a definition of the most frequent dynamic features of solid and cystic masses.

Update in Contrast-Enhanced Ultrasound [PDF]

open access: yesVisceral Medicine, 2020
<b><i>Background:</i></b> The aim of modern medicine is to safely classify diseases for successful therapy without invasive measures. Sonography, computed tomography (CT), and magnetic resonance imaging (MRI) are potent imaging techniques. However, without contrast medium, the informative value of the 3 native methods is limited.

Contrast-enhanced ultrasound in oncology [PDF]

open access: yesCancer Imaging, 2011
In patients with known malignant disease, 51% of liver lesions less than 1.5 cm turn out to be benign. Whether the probability of malignancy is high or low, further investigations are often necessary to definitely exclude malignancy. Contrast-enhanced ultrasonography has a prominent role in lesion characterization with a diagnostic accuracy comparable ...

Contrast-enhanced ultrasound of the spleen [PDF]

open access: yesUltrasound, 2016
Abnormalities in the spleen are less common than in most other abdominal organs. However, they will be regularly encountered by ultrasound practitioners, who carefully evaluate the spleen in their abdominal ultrasound studies. Conventional grey scale and Doppler ultrasound are frequently unable to characterise focal splenic abnormalities; even when ...

Novel use of contrast-enhanced ultrasound in the pretreatment planning prior to endovascular repair of endoleak after endovascular aortic aneurysm repair in a patient with chronic renal insufficiency: A case report and literature review

open access: yesJournal of Medical Ultrasound, 2022
Endoleaks are a common complication in patients who have undergone endovascular stent-graft repair of abdominal aortic aneurysms. The management of these complications depends on the type of endoleak seen at follow-up imaging, with embolization being ...

Clinical utility of combined contrast-enhanced ultrasound and intracavitary contrast-enhanced ultrasound in the percutaneous treatment of pyogenic liver abscess [PDF]

open access: yesExploration of Drug Science
Aim: This study aimed to evaluate the utility of the combined use of contrast-enhanced ultrasound (CEUS) and intracavitary CEUS (IC-CEUS) with diluted SonoVue in the management of percutaneous treatment for pyogenic liver abscess (PLA).

Contrast-Enhanced Ultrasound

open access: yesBioMed Research International, 2015
The recent decade has witnessed the great improvement of contrast-enhanced ultrasound (CEUS) and its extensive use in clinical practice, which is undoubtedly the major breakthrough in the field of diagnostic ultrasound in recent years. The concept of CEUS can be looked back to 60s in the last century, whereas only in 2000s CEUS regained increasing ...

Clinical Applications of Contrast-Enhanced Ultrasound in the Pediatric Work-Up of Focal Liver Lesions and Blunt Abdominal Trauma: A Systematic Review

open access: yesUltrasound International Open, 2017
In pediatrics ultrasound has long been viewed more favorably than imaging that exposes patients to radiation and iodinated contrast or requires sedation.
