Diagnostic Agent, Cardiac Function
Uses of This Medicine:
The albumin microspheres sonicated preparation is an ultrasound contrast agent. Ultrasound contrast agents are used to help provide a clear picture during ultrasound. Ultrasound is a special kind of diagnostic procedure. It uses high-frequency sound waves to create images or “pictures” of certain areas inside the body. The sound waves produced by the ultrasound equipment can be reflected (bounced off) by different parts of the body, like for example, the heart. As the sound waves return they are electronically converted into images on a television screen. Unlike x-rays, ultrasound does not involve ionizing radiation.
The albumin microspheres sonicated preparation contains very small gas-filled albumin microspheres that reflect the sound waves and help create a better picture. The albumin microspheres sonicated preparation is given by injection into a vein before ultrasound to help diagnose problems of the heart.
The albumin microspheres sonicated preparation is to be given only by or under the direct supervision of a doctor with specialized training in ultrasound procedures.
Before Using This Medicine:
In deciding to use a diagnostic test, any risks of the test must be weighed against the good it will do. This is a decision you and your doctor will make. Also, other things may affect test results. For this test, the following should be considered:

For non-prescription products, read the label or package ingredients carefully.
Studies on this agent have been done only in adult patients, and there is no specific information comparing use of albumin microspheres sonicated in children with use in other age groups.
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. There is no specific information comparing use of albumin microspheres sonicated in the elderly with use in other age groups.
