Figure 3 White matter changes on magnetic resonance imaging (MRI) in patients with lung cancer after radiation therapy to the entire brain. Analysis of 68 patients with lung cancer with brain metastases, including 37 treated with whole-brain radiation and stereotactic radiosurgery (SRS) and 31 control patients treated with SRS alone. Image review was blinded to the treatment cohort. The median and mode whole-brain radiation dose was 30 Gy over 10 fractions (range 20–37.5 Gy).
