What happens to radiopharmaceuticals once inside my body?

Hossein Jadvar (Doctor) gives expert video advice on: How are radiopharmaceuticals made?; What are examples of radiopharmaceuticals?; Are there radiation risks of radiopharmaceuticals? and more...

Once a radio-pharmaceutical is inside your body, basically it depends on the radio-pharmaceutical. The chemistry of the radio-pharmaceutical dictates how, basically it distributes in the body and they go to an appropriate place and accumulate there for us to be able to image them. For example, if we give a technician a ninety-nine system, amibbi which is for looking at profusion, for looking at how the heart muscle is being pro-fused, it basically goes to the heart muscle through the coronary arteries It distributes into the substance of the muscle. It happens that maybe in the system it goes to the myocardium which is the constituent of the cells and that's how it distributes into the myocardium. It does not change. It does not redistribute and we are able to make an image of the distribution in the myocardial which is dependent on how well that myocardial is being pro-fused. So, if it's not pro-fused well because of a problem or a disease in the coronary artery because of coronary artery disease, then the delivery of this tracer is reduced in the myocardial in that are of the myocardium and that's what we see and report as what we call ischemia. There's a shortage of blood to that area of the myocardium.
