Sonicated echocardiographic contrast agents: reproducibility studies.
This article describes the production, analysis, and reproducibility of forming microbubbles for contrast ultrasound imaging. The sonication method used to generate microbubbles was tested by four independent observers, and a subsequent laser particle counter analysis of microbubble size and concentration determined the reproducibility of the method. The results indicated that the mean bubble s...
متن کاملEfficacy of prokinetic agents in diabetic gastroparesis comparing symptomatology and scintigraphy – An open-label trial
Background: It is pertinent to objectively assess the severity of diabetic gastroparesis and tailor treatment accordingly. The current study was planned to document gastroparesis by gastric emptying scintigraphy (GES) objectively and see the effect of medications and diet control on clinical and GES after four weeks. Methods: A prospective, open-label randomized trial was conducted in the Depa...
متن کاملImproving the evaluation of left ventricular systolic function with intravenous perfluorocarbon ultrasound contrast: will suboptimal echocardiograms become an endangered species?
Over the past five years, intravenous ultrasound contrast imaging has gone from a technique that had a few limited right-sided applications (e.g., detecting a patent foramen ovale) to one that has the potential to become an allencompassing imaging technique for both the determination of global and regional left ventricular (LV) systolic function and the rapid assessment of myocardial perfusion....
متن کاملEfficacy and adverse effects of transpulmonary contrast echocardiography using sonicated albumin.
We studied the feasibility and adverse effects of transpulmonary contrast echocardiography using sonicated albumin in 6 dogs. Left heart contrast was observed by two-dimensional echocardiography, monitoring left ventricular pressure, its first derivative (dP/dt) and arterial oxygen saturation. The left heart was adequately opacified in 48 of 55 injections of various intravenous doses of sonicat...
