While a CT scan generates a detailed view of the anatomy or structures of organs and tissues in the body, a PET scan provides information about your body on a cellular level. PET scans provide information on tissues/tumor metabolism and responses to certain treatments. When combined, these two state-of-the-art techniques provide valuable information to your physicians, which aids in diagnosis and treatment planning.
