Functional Imaging on MRIdian: High-value, Diffusion-weighted Imaging with Low-field MRI

MRIdian is the world’s first radiation therapy system to integrate a diagnostic-quality MRI with an advanced linear accelerator and the only system with MR-guided, real-time, 3D, multiplanar soft-tissue tracking and automated beam control. MRIdian offers precise and personalized care through on-table adaptive treatments without fiducials. The technological foundations of MRIdian allow for the delivery of ablative dose with tighter margins in five or fewer fractions, all while maintaining low to no toxicity. With tens of thousands of patients treated, and an ever-growing body of clinical evidence, MRIdian is leading the MRI-guided revolution in radiation therapy.

Diffusion-weighted imaging is an MRI technique that detects water molecule diffusion in tissues. The MRI applies magnetic gradients to create a map of the diffusion properties of tissues. During MR-guided radiation therapy with MRIdian, DWI imaging can help identify the extent of the tumor and any areas of abnormal diffusion of water molecules within the tumor. This information can help guide the radiation treatment plan and monitor the tumor's response to treatment.

Our customers will be sharing the newly enhanced DWI sequence on MRIdian, highlighting the precision and accuracy on a high-value low-field system, their initial results, and potential applications in radiotherapy.
