FDG-PET is an important tool for cervical cancer radiation treatment planning, both for external irradiation and brachytherapy. The ability of FDG-PET to accurately define the primary cervical tumor volume and areas of lymph node metastasis greatly facilitates radiation treatment planning. The information provided by FDG-PET has the potential to change treatment field size and/or dose parameters for cervical cancer patients. FDG-PET brachytherapy planning uniquely demonstrates the three-dimensional relationship of the cervical tumor, adjacent organs, and treatment applicators, which could allow for treatment optimization. Besides demonstrating valuable anatomic information, FDG-PET also provides functional information which has been shown to have prognostic value and represents another aspect of how FDG-PET can influence cervical cancer radiation treatment planning. FDG-PET, already a routine imaging tool, is likely to play a larger role for cervical cancer and radiation therapy treatment planning in the near future.
