 The primary goal of this pilot study is to assess the feasibility of using magnetic resonance MR imaging guidance in the Magnetic Resonance Therapy MRT unit at the Brigham and Womens Hospital during the implantation of brachytherapy applicators in patients with gynecologic malignancies. Patients with gynecologic malignancies requiring brachytherapy are currently treated under either fluoroscopic or CT visualization of the brachytherapy applicator. Magnetic resonance imaging has been shown in many studies to provide superior visualization of the cervix, vagina and uterus compared to CT. However no prior study has examined the feasibility of using real-time magnetic resonance imaging to assist in the guidance of gynecologic brachytherapy applicators
