INTRODUCTION Which kind of ultrasound imaging technique is suitable for the assessment of the abdominal aortic stiffness are seldom reported. The purposes of this study were to explore a reliable method to evaluate the abdominal aortic stiffness in patients with hypertension among the following ultrasound imaging techniques: M-mode ultrasonography (M-mode), tissue tracking and strain rate imagi...

Imaging techniques have been widely implemented to study the dynamics of chip formation. They can offer a direct method and full field measurement cutting process, providing kinematic information formation process. In this article, state art imaging reported in literature has summarized analyzed. The applied mechanism, friction behavior, strain/strain rate, stress fields. Furthermore, surface i...

Background—Magnetic resonance spectroscopy can quantify myocardial triglyceride content in type 2 diabetic patients. Its relation to alterations in left (LV) and right (RV) ventricular myocardial functions is unknown. Methods and Results—A total of 42 men with type 2 diabetes mellitus were recruited. Exclusion criteria included hemoglobin A1c 8.5%, known cardiovascular disease, diabetes-related...

OBJECTIVES The pixel velocity values obtained by color Doppler tissue imaging (DTI) can be processed to velocity gradients as a measure of longitudinal strain rate with a technique termed strain rate imaging (SRI). Color mapping of strain rate does show the spatial-temporal relations of the diastolic phases. The phases of early filling and late filling during atrial systole can be seen to consi...

Background: Trunk muscles play an important role in providing both mobility and stability during dynamic tasks in athletes.The purpose of this study was to evaluate the within-day and between-day reliability of ultrasound (US) in measuringabdominal and lumbar multifidus muscle (MF) thickness in athletes with and without hamstring strain injury (HSI).Methods: Fifteen male socce...

The use of hand-held ultrasound strain imaging for the intra-operative real-time visualization of HIFU (high-intensity focused ultrasound) ablations produced in the liver by a toroidal transducer was investigated. A linear 12 MHz ultrasound imaging probe was used to obtain radiofrequency signals. Using a fast cross-correlation algorithm, strain images were calculated and displayed at 60 frames ...

BACKGROUND In recent days, the prevalence of childhood metabolic syndrome (MS) has increased substantially due to the increasing rate of childhood obesity on a global scale. The aims of this study were to detect the important parameters and provide the screening system to prevent cardiovascular disease in adolescents with MS. METHODS Ninety one male adolescents were divided into two groups ba...

Segmental contractility can be assessed quantitatively by analyzing deformation, or strain, and the rate of deformation, or the strain rate. This type of analysis can be performed using either tissue Doppler imaging or, more recently, two-dimensional speckle-tracking echocardiography. The aim of this study was to determine typical parameter values in healthy subjects and their reproducibility. ...

The purpose of the current study was to compare right ventricular (RV) myocardial wall velocities (tissue Doppler imaging) and strain rate imaging (SRI) parameters with conventional echocardiographic indices evaluating RV function in chronic obstructive pulmonary disease (COPD) patients. In total, 39 patients with COPD and 22 healthy subjects were included in the current study. Seventeen patien...
