Metabolism and Toxicity of Metals,on, this chapter will review a number of mechanisms believed to be associated with observed echo-contrast effects. Emphasis will be on miscellaneous illustrative theoretical and experimental studies of gaseous microbubble dynamics in fluids and interactions of such bubbles with an ultrasound field.

We proceeded to record the aortic valve and root echo simultaneously with measurements of cardiac outputs using the indicator-dilution technique in the cardiac catheterization laboratory.

Structural Aspects of Metal Toxicity,plications of contrast echocardiography are still expanding, since numerous studies have shown its efficacy and safety. The committee on contrast echocardiography for the American Society of Echocardiography found only 32 cases of possible (always transient) toxicity out of 13,946 examinations surve

This role is comparable to that of iodine in X-ray contrast media and of gadolinium in magnetic resonance contrast media [1, 2, 31]. However, single microbubbles, without any additional protection against gas

They have been used clinically to verify the presence of intracardiac shunts [2] and valvular regurgitations [3, 8] and for the measurement of cardiac output [9]. Contrast echocardiogr
