Magnetic Resonance-guided Radiation Therapy

Magnetic Resonance-guided Radiation Therapy (MRgRT) uses magnetic resonance imaging (MRI) together with a linear accelerator (Linac) to locate tumors needing treatment throughout the body.

At the Sidney Kimmel Cancer Center our highly trained Radiation Oncology clinical care team of experts consisting of therapists, dosimetrist, physicists and physicians are able to ensure safe and effective treatment on the MRLinac with more accuracy than ever before, especially when treating tumors that may move during radiation delivery. 

Natural body functions such as digestion and breathing cause normal and target tissue motion, this motion can make it difficult to precisely focus the radiation beam.  The MRI system can image and adjust while the machine is delivering this beam so that corrections can be made in real-time to its target area.

The MRI machine provides us a real-time view of the surrounding organs and soft tissue, allowing the clinician to actively track the position of the tumor during treatment and adapt to these movements to target and treat the tumor with precision.

Therefore our expert clinicians can adapt each patient's individualized treatment plan based on changes in tumor location or shape, as well as changes in surrounding organs or tissue.  

This type of radiation therapy can improve outcomes for hard to treat tumors.  MRgRT is not only convenient for patients, as they are done in shorter radiation courses, but it also optimizes efficacy in overall cancer care.
