Autosomal dominant polycystic kidney disease - Type 2. Ultrasound, genetic and clinical correlations
(2000)Background. Ultrasound, genetic and clinical correlations are available for ADPKD-1, but lacking for ADPKD-2. The present study was carried out to address: (i) the age-related diagnostic usefulness of ultrasound compared ...

Dynamic contrast enhanced ultrasound assessment of the vascular effects of novel therapeutics in early stage trials
(2012)Imaging is key in the accurate monitoring of response to cancer therapies targeting tumour vascularity to inhibit its growth and dissemination. Dynamic contrast enhanced ultrasound (DCE ultrasound) is a quantitative method ...

Article
An effective ultrasound video communication system using despeckle filtering and HEVC
(2015)The recent emergence of the high-efficiency video coding (HEVC) standard promises to deliver significant bitrate savings over current and prior video compression standards, while also supporting higher resolutions that can ...

Article
First and second order statistical texture features in carotid plaque image analysis: preliminary results from ongoing research.
(2011)Carotid plaques have been associated with ipsilateral neurological symptoms. High-resolution ultrasound can provide information not only on the degree of carotid artery stenosis but also on the characteristics of the ...

Article
An integrated system for the segmentation of atherosclerotic carotid plaque ultrasound video
(2014)The robust border identification of atherosclerotic carotid plaque, the corresponding degree of stenosis of the common carotid artery (CCA), and also the characteristics of the arterial wall, including plaque size, ...

Intussusception of the bowel in adults: A review
(2009)Intussusception of the bowel is defined as the telescoping of a proximal segment of the gastrointestinal tract within the lumen of the adjacent segment. This condition is frequent in children and presents with the classic ...

Manual and automated media and intima thickness measurements of the common carotid artery
(2009)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of the development of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the media ...

Media thickness measurement of the common carotid artery.
(2007)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of the development of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the media ...

Article
Multiscale amplitude-modulation frequency-modulation (AM-FM) texture analysis of ultrasound images of the intima and media layers of the carotid artery
(2011)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). Clinically, there is strong interest in identifying how the composition and texture ...

Article
Robust and efficient ultrasound video coding in noisy channels using H.264.
(2009)In this paper we define diagnostic Regions of Interest (ROIs) for carotid ultrasound medical video, which we then use as input for Flexible Macroblock Ordering (FMO) slice encoding. We extend the FMO concept by enabling ...

Second-harmonic generation in a sound beam reflected and transmitted at a curved interface
(2000)This article presents a model for second-harmonic generation in a sound beam that is reflected from or transmitted through a curved interface. Propagation in homogeneous fluids is assumed. Simple analytic solutions are ...

Article
Texture-based classification of atherosclerotic carotid plaques
(2003)There are indications that the morphology of atherosclerotic carotid plaques, obtained by high-resolution ultrasound imaging, has prognostic implications. The objective of this study was to develop a computer-aided system ...

Article
Vascular flow and perfusion imaging with ultrasound contrast agents
(2004)Current techniques for imaging ultrasound (US) contrast agents (UCA) make no distinction between low-velocity microbubbles in the microcirculation and higher-velocity microbubbles in the larger vasculature. A combination ...
