OBJECTIVE The purpose of this meta-analysis was to compare outcomes for AngioJet thrombectomy versus percutaneous coronary intervention (PCI) without thrombectomy in acute myocardial infarction (AMI) patients. BACKGROUND PCI is the preferred treatment for revascularizing the infarct-related artery in patients with AMI. There is controversy about the(More)
BACKGROUND Near-infrared spectroscopy-derived tissue hemoglobin saturation (StO2) is a noninvasive measurement that reflects changes in microcirculatory tissue perfusion. Previous studies in trauma patients have shown a correlation between low StO2 levels and mortality, organ failure, and severity of injury. The goals of this study were to identify the(More)
Cardiac anatomy is complex and often difficult to visualize or comprehend. 3D echocardiography is an area undergoing rapid development that represents a natural extension of conventional sonography methods which require integrating a series of 2D image slices to develop a 3D impression of underlying anatomy or pathology. This paper will review some of the(More)
The accurate measurement of cardiac chamber volume is of major importance in assessing cardiac performance. Accurate equilibrium radionuclide volume estimations are difficult to obtain, due to the geometry of the chambers, and the physical characteristics of the imaging system. The purpose of this study was to examine the effects of imaging projections on(More)
OBJECTIVE To statistically evaluate published clinical efficacy data related to the use of pulsed radio frequency energy (PRFE) therapy in 3 clinical applications. BACKGROUND Numerous clinical studies have reported efficacy outcomes for PRFE therapy use in the palliative treatment of both postoperative and nonpostoperative pain and edema, and for its use(More)
Fractal organization and behavior is an important and ubiquitous feature of biologic systems. Recognition of the properties and scaling relations can yield important clues regarding the underlying anatomy and physiology of most organs. Potential applications are many, and this brief article has considered only a few areas where there has been progress to(More)
The aim of this study was to describe the potential of three-dimensional ultrasound (3D US) in paediatric and neonatal neurosonography. The potential applications are illustrated based on our experience in 150 patients using three different 3D US techniques at two different sites. Various disease entities throughout the paediatric age have been evaluated.(More)

The complex anatomy and dynamics of the heart make it a challenging organ to image. The fetal heart is particularly difficult because it is located deep within the mother's abdomen and direct access to electrocardiographic information is difficult. Thus more complex imaging and analysis methods are necessary to obtain information regarding fetal cardiac(More)
