简要总结
This study will see whether the addition of more frequent planning CTs during the course of radiation, and of Positron Emission Tomography (PET), a diagnostic test similar to CT, prior to and during a course of radiation may provide information that could potentially be used during the treatment to improve the initial radiation plan.
