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 ...

Computerized texture analysis of carotid plaque ultrasonic images can identify unstable plaques associated with ipsilateral neurological symptoms
(2011)We estimated the value of objective, computerized texture analysis of ultrasonic images in distinguishing carotid plaques associated with neurological ipsilateral symptoms (amaurosis fugax [AmF

Article
Effect of zooming on texture features of ultrasonic images
(2006)Background: Unstable carotid plaques on subjective, visual, assessment using B-mode ultrasound scanning appear as echolucent and heterogeneous. Although previous studies on computer assisted plaque characterisation have ...

Juxtaluminal hypoechoic area in ultrasonic images of carotid plaques and hemispheric symptoms
(2010)Objectives: The aim was to determine the diagnostic value of a juxtaluminal black (hypoechoic) area without a visible echogenic cap (JBA) in ultrasonic images of internal carotid artery plaques. Methods: Ultrasonic images ...

Manual and automated intima-media thickness and diameter measurements of the common carotid artery in patients with renal failure disease
(2014)The objective of this study was to investigate differences in intima-media thickness (IMT) and diameter (D) measurements of the common carotid artery (CCA) in ultrasound imaging in normal subjects and renal failure disease ...

Plaque imaging using ultrasound, magnetic resonance and computer tomography: A review
(2005)Different classifications have been proposed in the literature for the characterization of atherosclerotic plaque morphology, resulting in considerable confusion. For example plaques containing medium of high level uniform ...

Real-Time Adaptation to Time-Varying Constraints for Medical Video Communications
(2017)The wider adoption of mobile Health (mHealth) video communication systems in standard clinical practice requires real-time control to provide for adequate levels of clinical video quality to support reliable diagnosis. The ...

A review of noninvasive ultrasound image processing methods in the analysis of carotid plaque morphology for the assessment of stroke risk
(2010)Noninvasive ultrasound imaging of carotid plaques allows for the development of plaque-image analysis methods associated with the risk of stroke. This paper presents several plaque-image analysis methods that have been ...

Article
Tissue harmonic ultrasonic imaging
(2001)Harmonic imaging was originally developed for microbubble contrast agents in the early 90s under the assumption that tissue is linear and all harmonic echoes are generated by the bubbles. In fact, tissue, like bubbles, is ...

Ultrasound image quality evaluation
(Institute of Electrical and Electronics Engineers Inc., 2003)The objective of this work was to evaluate the image quality of two different ultrasound image scanners before and after de-speckle filtering. The evaluation was made by statistical and texture analysis, as well as by ...

Article
Ultrasound image texture analysis of the intima and media layers of the common carotid artery and its correlation with age and gender
(2009)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the composition and texture of ...

Ultrasound imaging in the analysis of carotid plaque morphology for the assessment of stroke
(2005)The aim of this chapter is to summarise the recent advances in ultrasonic plaque characterisation and to evaluate the efficacy of computer aided diagnosis based on neural and statistical classifiers using as input texture ...
