Understanding Allergic Airway Diseasesctively without a basic understanding of this interaction and how it is exploited by the new imaging modes that have become available on modern ultrasound systems. In this chapter we consider how echocardiography might benefit from a contrast agent, describe currently available agents and explain th

The Changing Financial Landscape,ed in each cardiac patient. Earlier, research and development of diagnostic measures concentrated on systolic LV function, because diastole was thought to be a passive process, which is now known not to be the case. However, it is still easier to evaluate systolic than diastolic function. In the phy

What Is an Analog Side Channel?,ture contrast echo will replace scintigraphy as the reference method for perfusion imaging. This optimism is based on widespread experience with intracoronary contrast echocardiography where optimal imaging conditions are found. For intravenous contrast perfusion imaging, we hope that the following

Though attenuation and other technical factors preclude estimation of the absolute concentration of bubbles from the echo amplitude alone, relative changes in bubble concentration in a region of the image can be estimated from the echo signal itself. Knowing this value enables a
