Radiation serves an important role in the treatment of metastatic and primary brain tumors. Radiation carries a risk of post radiation treatment effects, such as pseudoprogression and radiation necrosis. The ability to differentiate between radiation necrosis, pseudoprogression, and tumor recurrence remains a diagnostic conundrum with varying treatment options. In this review, we will discuss the pathophysiology, diagnostic imaging modalities, and treatments of these post-radiation treatment effects. We focus on the latest developments in magnetic resonance imaging (MRI) modalities including imaging biomarkers and the newest therapeutics such as VEGF inhibitors, Hyperbaric Oxygen Therapy, sensitized cytotoxic T cells, and Laser Interstitial Thermal Therapy (LITT).
