The advantages of Diffusion Weighted Imaging in Elekta Unity

Learn more about the advantages of using Diffusion Weighted Imaging (DWI), which assesses tumor response during the course of treatment

Advantages of DWI in RT:

• DWI helps monitor and predict therapy response more effectively than tumor size alone.
• Functional MRI is used to predict therapy outcomes, with the MR-Linac enabling real-time response tracking.

Using DWI for the Brain:

•  DWI provides functional information on lesions, helping to extract biomarkers that guide treatment modifications for better patient outcomes.

Why 1.5T MRI?

• Functional imaging with 1.5T MRI allows personalized treatments based on changes in diffusion and ADC maps.

Clinical experience:

• Standard fractionated treatments with concurrent chemotherapy were delivered.
• Additional imaging with  Elekta Unity showed strong correlation with reference scanner results.
• Notable decrease in diffusion restriction as an early sign of radiation response.
• Future use of this data will enable real-time treatment adaptation based on therapy response.
