The goal of this trial is to assess how magnetic resonance imaging (MRI) may be used to improve tumor and normal tissue volume delineation, reducing toxicity and recurrence in gynecologic brachytherapy. To analyze the correlation of T2 and diffusion weighted MR-imaging characteristics with pathologically determined markers of proliferation, the Investigators will biopsy tissue at the time of brachytherapy.
The Investigators will compare dosimetric values to the organs at risk (OAR) with CT versus MRI planning. The Investigators anticipate that MR-planned cases will have lower OAR doses than standard CT-based cases due to more conformal planning. The Investigators will determine dose thresholds for radiation-related toxicity after treatment. The Investigators will compare toxicity rates at 6 months, 1 and 2 years after treatment, thereby enabling improved recommendations on dose limits to the OAR.

- Dosing changes [ Time Frame: 3 years ]To quantify the relative reduction of dose to rectum, sigmoid and bladder obtained after MR Simulator Suite-guided placement, as compared to standard CT guided treatment based on historical information and literature review.
- The rate of treatment-related toxicity [ Time Frame: 3 months, 6 months and 1 year ]To determine the rate of treatment-related toxicity within 3 months, 6 months and 1 year after MR Simulator Suite-guided placement.
- Time to local failure [ Time Frame: 1 year and 2 year ]To determine the local failure rates at 1 year and 2 year after MR Simulator Suite-guided placement.
- Rate of survival [ Time Frame: 1 year and 2 year ]To determine the overall survival rates at 1 year and 2 year after MR Simulator Suite-guided placement.
