Abstract:
PET/CT imaging has rapidly emerged as an important imaging tool in oncology. The success of PET/CT imaging is based on several features. First, patients benefit from a comprehensive diagnostic anatomical and functional (molecular) whole-body survey in a single session. Second, PET/CT provides more-accurate diagnostic information than PET or CT alone. Third, PET/CT imaging allows radiation oncologists to use the functional information provided by PET scans for radiation treatment planning. In this Review we discuss the technical features of PET/CT, its economic aspects within the health-care system, and its role in diagnosis, staging, restaging and treatment monitoring as well as radiation planning in patients with cancer.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
