Acoustic detection of microbubble resonance
(2009)Large numbers of acoustic signals from single lipid-shelled Definity (R) microbubbles have been measured using a calibrated microacoustic system and a two population response observed. Theoretical results based on the ... -
The acoustic signature of decaying resonant phospholipid microbubbles
(2013)Sub-capillary sized microbubbles offer improved techniques for diagnosis and therapy of vascular related disease using ultrasound. Their physical interaction with ultrasound remains an active research field that aims to ... -
Carotid plaque composition in stable and unstable coronary artery disease
(2005)Background Several pieces of evidence suggest that formation of complex atheromatous plaques may be influenced not only by local but also by systemic factors. Methods Twenty-five patients (16 men/9 women, age 63 +/- 10 ... -
Common femoral artery intima-media thickness as marker for cardiovascular disease in asymptomatic adults
(2009)Background: The common carotid intima-media thickness (IMT) is considered as a marker of cardiovascular disease, while the value of the common femoral IMT is not well defined. The aim of the present study was to investigate ... -
Comparison between clinical and ultrasonographic assessment in patients with erosive osteoarthritis of the hands
(2010)The objective of this study is to assess the reliability of clinical examination in patients with erosive osteoarthritis (EOA). Eighteen patients with EOA underwent clinical examination for joint tenderness, bony swelling, ... -
Comparison between ultrasonographic and caliper measurements of testicular volume in the dog
(2008)The aim of this study was to compare the accuracy of two methods used to clinically estimate testicular volume in the dog. Caliper and ultrasonographic measurements of testicular dimensions (length, width and height) of ... -
Experimentally induced orchitis associated with Arcanobacterium pyogenes: clinical, ultrasonographic, seminological and pathological features
(2004)The objectives of this study were to describe the features of experimentally induced orchitis associated with Arcanobacterium pyogenes and confirm the pathogenicity of the organism for the ovine testicle. One testicle of ... -
Gray and Color Doppler Ultrasonography in differentiation between chronic viral hepatitis and compensated early stage cirrhosis
(2007)Aim. To assess the value of Gray scale (GS) and Colour Doppler Ultrasonography (CDU) in differentiating the progression of chronic viral hepatitis (CVH) and compensated liver cirrhosis (CIR). Patients and methods. Seventy-two ... -
Imaging modalities for renal artery stenosis in suspected renovascular hypertension: Prospective intraindividual comparison of color Doppler US, CT angiography, GD-enhanced MR angiography, and digital substraction angiography
(2007)The aim of the study was to evaluate the diagnostic accuracy of Color Doppler US, CT Angiography (CTA), and GD-enhanced MR Angiography (MRA) compared with digital subtraction angiography (DSA) for the detection of renal ... -
Parametric stability and dynamic buckling of an encapsulated microbubble subject to acoustic disturbances
(2011)Stability analysis of the radial pulsations of a gas microbubble that is encapsulated by a thin viscoelastic shell and surrounded by an ideal incompressible liquid is carried out. Small axisymmetric disturbances in the ... -
Postoperative stroke in cardiac surgery is related to the location and extent of atherosclerotic disease in the ascending aorta
(2001)OBJECTIVES The aim of the study was to evaluate the risk from calcified atheromas in the ascending aorta, and the extent and topography of the disease in the development of stroke after cardiac surgery. BACKGROUND Postoperative ... -
Simulations of insonated contrast agents: Saturation and transient break-up
(2013)Under insonation contrast agents are known to perform nonlinear pulsations and deform statically, in the form of buckling, or dynamically via parametric mode excitation, and often exhibit jetting and break-up like bubbles ... -
Sonographic assessment of changes in diaphragmatic kinetics induced by inspiratory resistive loading
(2013)Background and objective: Diaphragmatic breathing patterns under resistive loading remain poorly documented. To our knowledge, this is the first study assessing diaphragmatic motion under conditions of inspiratory resistive ... -
Sonographic detection of vesicoureteral reflux with fluid and air cystography. Comparison with VCUG
(1996)Purpose: Attempt to find out an effective and reliable alternative method for the diagnosis of vesicoureteral reflux (VUR), without irradiation, in children, and the comparison of its results with those of voiding ... -
Tumors and tumor-like lesions mimicking carpal tunnel syndrome
(2014)Tumors and tumor-like lesions in or around the median nerve are uncommon causes of carpal tunnel syndrome (CTS). The purpose of the present study is to highlight the diagnostic approach and point out the profile of patients ... -
Ultrasonographic appearance of clinically healthy testicles and epididymides of rams
(2003)The clinically healthy testicles and epididymides of 31 rams were imaged inside and outside the breeding period, by using a real time ultrasound scanner. A scanning technique based on multiple imaging planes from the caudal ... -
Ultrasonography in differentiation between chronic viral hepatitis and compensated early stage cirrhosis
(2008)AIM: To assess the value of gray scale (GS) and colour Doppler ultrasonography (CDU) in differentiating the progression of chronic viral hepatitis (CVH) and compensated liver cirrhosis (CIR). METHODS: Seventy-two patients ...
