Details and patient eligibility

About

The standard treatment for cervix cancer at Princess Margaret Hospital is external radiation with chemotherapy followed by internal radiation, called brachytherapy. Currently, brachytherapy treatment is planned on a type of Magnetic Resonance Imaging (MRI) called T2-weighted (T2W) MRI.

The main purpose of this study is to determine whether the following imaging tests can visualize the tumor better for planning the brachytherapy treatment:

  1. special types of MRI called diffusion weighted MRI (DWI) and dynamic-contrast enhanced MRI (DCE-MRI); and
  2. an x-ray test called positron emission test (PET) performed with a sugar dye called FDG. MRI-guided brachytherapy is resource-intensive and not widely available.
