PET-CT is a non-invasive medical imaging process which uses small amounts of radioactive material to diagnose a variety of diseases including cancer, Alzheimer's and heart disease. The PET portion measures important body functions such as blood flow, oxygen use, and sugar (glucose) metabolism. These images are then combined with CT, which shows the anatomy of the body, to pinpoint with great accuracy the functionality of specific organs and tissues.
PET-CT has revolutionized many fields of medical diagnosis, by adding precision of anatomic localization to functional imaging. Installed in 2003 along with a cyclotron (the machine used to create the radiopharmaceuticals used for PET imaging), MSU was the first radiology department in the Lansing area to house a permanent PET-CT scanner.
