 Magnetic resonance imaging MRI is currently one of the standard diagnostic imaging methods used to diagnose tumor stage before treatment in Radiology Oncology Department. It is also used to check responses to radiation after treatment. However, MRI isnt traditionally used in planning for radiation treatment or in checking treated tumor and tissue changes during radiation treatment. The goal is to find out the possible benefits of MRI imaging techniques in these settings of radiation treatment. Participating in this study would NOT change the current treatment plans, this will allow the investigators to use the MRI methods in research and future patient care.
