This is a Nuclear Medicine test to see the perfusion of radioactive isotope to the muscles of the heart. The isotope Technetium 99m is attached to a pharmaceutical (the tetrofosmin) that has an affinity with the cardiac muscle . The myocardium is the name for the heart muscle. Perfusion equals flow of blood to the tissues. In patients with acute heart problems, they often just do a resting study - patients get injected and the heart is imaged using a gamma camera. For most patients, they try to do a rest and exercise test, to see the difference in isotope distribution (and hence blood flow) to the heart in different states. The same sort of Nuclear Medicine test can be done using another isotope called Thallium. A more sensitive medical imaging type of test gauging cardiac blood flow is a PET scan using FDG. But it's a more expensive and a rarer procedure. Sorry to interrupt. I was just perusing over some medical imaging stocks on SI and found this one. Just took a little time out to answer your question. I might lurk for a while and find out a little more about this company - sounds kinda interesting. Regards, Durro
