Molecular imaging enables earlier, individualized treatment of thyroid cancer Jan 3, 2009
In addition to emitting electrons that destroy the tissue harboring the radionuclide, radioactive iodine emits photons suitable for imaging. "Normal thyroid tissue as well as residual cancer cells concentrate radioiodine. Performed after ingestion of radioiodine, SPECT-CT provides three-dimensional images of the distribution of the radionuclide in the human body and is therefore used for staging this type of cancer," said Torsten Kuwert, MD, co-author of the article.

Robert Beck, at 80; leader in early work on radioactive materials for medical imaging Aug 19, 2008
After Harper's team injected the isotope, also known as a radiotracer or radionuclide, into a patient, it could be tracked through the bloodstream and eventually to the heart, liver, and other organs. In 1963, the team conducted a scan of the human brain, and technetium-99 became an accepted diagnostic tool for finding tumors and other masses. (Boston Globe)

Researchers wake up viruses inside tumors to image and then destroy cancers Mar 1, 2007
For imaging purposes, FIAU can carry a radionuclide that emits a low energy gamma photon, but it can also be engineered to carry therapeutic radionuclides, which are lethal to cells in which TK is activated. Results of this study suggests that this strategy could be applied to other viruses associated with tumors, and that other drugs may potentially be used to activate these viruses, Pomper says.
