Figure 1. Selected case of large brain metastases treated with hypofractionated stereotactic radiation.

A. MRI of 3.6cm right cerebellar metastases from lung cancer. B. Highly conformal treatment plan with the 100% (green line) and 80% (blue line) isodose lines wrapping tightly around the gross tumour (red colorwash), and planning target volume (orange colorwash). The brainstem (blue colorwash) is spared from high dose. (B) MRI 2 months post completion of radiation (30Gy in 5 fractions). C. Complete resolution of the tumour at 1 year.
