Stroke Neuroimaging (IMAGE) Washington University School of Medicine Caption Scans of a stroke patient's brain show the area where tissue has died (magenta) and where tissue is damaged but may still be saved with prompt intervention (green). A study from Washington University School of Medicine in St. Louis has found that stroke evaluations fell by nearly 40% during a period of the COVID-19 pandemic, suggesting that many stroke patients are not seeking potentially life-saving medical treatment.
