For decades, intracavitary brachytherapy (ICBT) treatment planning for cervix cancer has been based on planar x-ray imaging, which was limited to the definition of dose tracking points relative to radiopaque structures, e.g., the implant and the bony anatomy. Around the 1990s, some clinics transitioned to computed-tomography (CT) imaging for ICBT, facilitating visualization of the applicator in the uterus and contouring of the organs at risk, but still limited with regard to delineation of the tumor volume itself. More recently, some clinics have begun using magnetic resonance (MR) imaging for ICBT treatment planning, enabling visualization of the tumor. In this session we will review the clinical aspects of MR image-based ICBT of cervix cancer with regard to target volume definition, dosimetry, and clinical outcomes. Then we will describe the implementation of some of these concepts into a multi-sequence MR image-based technique for target definition and adaptive ICBT planning. Finally, this session will discuss the quality assurance (QA) and commissioning requirements for MR image-based ICBT.
Learning Objectives:
1. Understand the clinical aspects of MR image-based ICBT treatment of cervix cancer
2. Understand how MR imaging can be used for target definition and adaptive ICBT treatment planning.
3. Understand the QA and commissioning process for MR image-based ICBT
