Magnetic Resonance Imaging of Endometrial and Cervical Cancer

In this article we review the current and developing roles of magnetic resonance imaging (MRI) in endometrial and cervical cancer. In endometrial cancer, the purpose of MRI is to stage the primary tumor and in particular to identify myometrial and cervical invasion and extra-uterine disease, thereby informing preoperative surgical planning. MRI is also used to safely select young patients suitable for fertility-preserving medical management. In cervical cancer, MRI has an established role in local staging and in assessing proximal extension of tumors in young women for feasibility of fertility-preserving surgery. It is used to plan radiotherapy for primary tumors in cervical cancer and particularly for conformal radiotherapy to deliver optimal doses to the tumor sites, while limiting unwanted exposure of bowel and other pelvic organs. In both cancers, MRI is used for diagnosing nodal disease, surveillance, detection of recurrence, and evaluation of complications secondary to treatment.
