positron emission tomography/computed tomography (PET/CT)
PET/CT combines two state-of-the-art technologies in one. PET highlights the abnormal metabolic function of cells. CT simultaneously depicts the anatomical location of the cells with precision and clarity.
Together, these images create a 3-D picture that enables physicians to make better decisions for earlier cancer treatment. PET/CT is also useful for following response to therapy and allows early detection of cancer recurrence, which can improve the chances of treatment success.
The PET/CT injection utilizes radioactive glucose. It is not iodine and there is no reaction with diabetic medications.
