I have been asked by a cardiologist to perform a renal artery study on a
patient that he says is large and has poor renal functions therefore cannot
undergo angiography. He would like for me to give the patient the drug
Optison (human albumin microspheres) if I am unable to adequately visualize
the renal arteries. According to the literature, this is successfully used
during echocardiography when the outline of the heart is not adequately
visualized. It is excreted through the lungs rather than the kidneys. The
literature does not state that it works the same for visualization of the
Does anyone have any experience with or knowledge of this drug?
