Introduction: Some recent studies have shown that citicoline improves clinical symptoms in patients with stroke. Citicoline's mechanism of action in improving the clinical symptoms is not recognized yet. The aim of this study was to evaluate the cerebrovascular hemodynamic status in patients with ischemic stroke treated with citicoline compared with the control group. <st...

Limited bandwidth, multipath-induced signal fading, and motion-induced Doppler effect makes underwater acoustic (UWA) communication still an ongoing challenge. Among numerous interesting researches on UWA communication, the application of orthogonal signal division multiplexing (OSDM) has been proposed by authors. In our previous work, it was found that the UWA communication with OSDM achieves ...

In this paper, an overview of Doppler ultrasound quality assurance (QA) testing will be presented in three sections. The first section will review the different Doppler ultrasound parameters recommended by professional bodies for use in QA protocols. The second section will include an evaluation and critique of the main test devices used to assess Doppler performance, while the final section of...

BACKGROUND Hand held Doppler ultrasound machines are routinely used by podiatrists to assess the arterial perfusion of the lower limb. They are practical, painless and effective as a screening tool, and the available general evidence would suggest that interpretation by practitioners is reliable. This study compared the abilities of student and Health and Care Professions Council (HCPC) registe...

OBJECTIVES To determine if tumor vascularity as assessed by three-dimensional (3D) power Doppler ultrasound can be used to discriminate between benign and malignant ovarian tumors, if adding 3D power Doppler ultrasound to gray-scale imaging improves differentiation between benignity and malignancy, and if 3D power Doppler ultrasound adds more to gray-scale ultrasound than does two-dimensional (...

Introduction: Tracking muscle movement can be very useful in diagnosis and rehabilitation of patients with neuromuscular disorders. Doppler ultrasound is well suited for analysis of musculoskeletal movement, but conventional ultrasound systems are bulky and not suitable for monitoring patients during ambulatory gait. A wireless Doppler ultrasound system can allow for direct measurement of muscu...

conclusions the clinical features are effective indicators for distinguishing ihh from hbl, and the spectral doppler may be a useful adjunct parameter for differential diagnosis. objectives to study the clinical manifestations and the ultrasound features of the pediatric patients for distinguishing ihh from hbl. patients and methods between 2002 and 2012, thirteen children with ihh and 38 child...
