Interventions
MRI-guided adaptive stereotactic ablative body radiotherapy (SABR)
A single fraction of MRI-guided adaptive stereotactic ablative body radiotherapy (SABR) will be delivered using the MRIdian system. Treatment includes adaptive planning based on daily MRI imaging to update tumor and organ-at-risk contours and optimize the radiation dose. On the day of treatment, Eovist contrast is administered 20 minutes before therapy to enhance tumor visualization. Patients perform an inspiratory breath hold during radiation delivery to minimize motion. The total dose is 30-40 Gy delivered in one fraction using external beam techniques.
