The camera then records how the chemical interacts with the targeted tissue or bone. That's the same as one grain of salt. And that small amount is temporarily made radioactive only for about six hours. As a comparison, Mr. Stark notes a recent study in which a patient inhaled radioactive gas so doctors could search for blood clots in the lung. They are looking for what is there, and not how it functions.
Nuclear medicine is all about how something functions.
He continues his explanation, using a CAT-scan as an example. Nuclear medicine would be able to detect the dead heart muscle because the temporarily radioactive chemical injected into the body would be taken up by the heart's living tissue, thereby revealing the dead area. Iain is the kind of guy who'll wake up in the middle of the night with a great idea and then get to work on it right away. Dr. Powell is also a key investor in IS2. Mr. Stark, who has 11 patents relating to his scientific inventions, began his career in 1968 as production co-ordinator with a British firm that made a host of products ranging from the first commercial ultrasound equipment to instruments used to test the thickness of paper.
