Brain tumors are usually subjected to radiation therapy upon diagnosis. In this work, it is made an attempt at investigating if this therapy might cause injury to the non-cancerous parts of the brain. To this end dynamic contrast-enhanced MRI was used to estimate leakage across the blood-brain barrier.22 patients were imaged before and after undergoing a treatment schedule, and findings from the two examinations were compared to uncover any change. The data shows no significant variation in either permeability or blood plasma volume.
