| The IU School of Medicine will soon have the third PET/CT system in the country. A diagnostic tool, it makes earlier detection and more accurate diagnosis of cancer, cardiovascular and neurological diseases possible along with improved therapy and monitoring. This new technology actually combines two of the main imagining techniques already existing. PET imaging uses radiopharamceutical tracers in the body that measure metabolic, biochemical and function activity in living tissue. CT—more commonly called a CAT scan—produces images showing body structure and abnormalities not seen on X-rays. It can, for example, tell whether chemotherapy is effective in cancer cases within a few weeks.
