MRI and PET Imaging in Predicting Treatment Response in Patients With Stage IB-IVA Cervical Cancer

OUTLINE: Patients undergo radiation therapy and receive chemotherapy per standard of care. Patients undergo dynamic contrast-enhanced (DCE) MRI, diffusion-weighted (DW) MRI, and magnetic resonance (MR) spectroscopy at baseline, 2-2.5 weeks, 4-5 weeks, and 1 month following radiation therapy completion, and fludeoxyglucose F 18 (FDG) PET/computed tomography (CT) at baseline, 2-2.5 weeks, and 4-5 weeks. After completion of study, patients are followed up at least every 3-6 months for 5 years.
