Learning objectives

  • Discuss the role and benefits of MRI in planning for brachytherapy treatment in cervical cancer.

  • Discuss the key mechanisms of the applicator and the technical aspects of planning brachytherapy.

  • Discuss the role of MRI imaging in recognising the features of appropriate applicator placement and common complications.

  • Review key MRI features of radiation-related alterations in the pelvis post treatment and tumour response assessment.

Contents

  • Anatomy of the female pelvic organs on MRI

  • Key MRI imaging features of cervical cancer on MRI

  • Review the staging of cervical cancer amenable to brachytherapy (FIGO)

  • Advantages of brachytherapy versus external beam radiotherapy in treating cervical cancer.

  • Technical aspects of applicator selection and positioning in brachytherapy.

  • MRI features in assessment of appropriate placement of brachytherapy device, recognition of “organs at risk”.

  • Benefits of MRI versus more traditional imaging techniques CT and Radiographs, in brachytherapy planning.

  • “Red flag” features of brachytherapy device misplacement in MRI.

  • Features of tumour response and target organ assessment.

  • Complications of brachytherapy including post radiation fibrosis.

Conclusion

  • Analysis of MRI findings at the time of brachytherapy with the applicator is essential in the assessment of gross tumour volume, clinical target volumes and patho-anatomical structures.

  • T2-weighted MR images minimise potential misinterpretation due to partial volume effects, which improves depiction of tumour in parametria, vaginal fornices, and cervix.
