Use of PET/CT scanning in cancer patients: technical and practical considerations

Proc (Bayl Univ Med Cent). 2005 Oct;18(4):321-30. doi: 10.1080/08998280.2005.11928089.


This overview of the oncologic applications of positron emission tomography (PET) focuses on the technical aspects and clinical applications of a newer technique: the combination of a PET scanner and a computed tomography (CT) scanner in a single (PET/CT) device. Examples illustrate how PET/CT contributes to patient care and improves upon the previous state-of-the-art method of comparing a PET scan with a separate CT scan. Finally, the author presents some of the results from studies of PET/CT imaging that are beginning to appear in the literature.
