MRI-Guided Planning for Pelvic BrachytherapyFlorian Putz, M.D.

At University Hospital Erlangen, Germany, MRI plays a central role in the planning of pelvic brachytherapy. After applicator implantation, a planning MRI is performed on the 1.5T MAGNETOM Sola RT Pro Edition, conveniently located within the radiation oncology department to enable streamlined workflow between the procedure area and HDR treatment rooms.

PD Dr. Florian Putz, senior physician and leader of the MR-in-RT working group at University Hospital Erlangen, shares the MRI protocols used for pelvic brachytherapy. Developed in accordance with the GEC-ESTRO recommendations [1], these protocols include 3D sequences such as T2-SPACE and T1-VIBE Dixon. Together, they provide excellent visualization of the target volume, organs at risk (OARs), and applicators, supporting accurate and reproducible treatment planning.

These guidelines offer a valuable foundation for institutions seeking to establish standardized MR imaging workflows in pelvic brachytherapy.
