Dr. Claudia Kirsch joins Rethink Imaging to discuss how viruses like SARS-CoV-2 reshape the brain through inflammation, vascular injury, and immune pathways. From unexplained smell loss to the discovery of the nervus terminalis as a potential viral pathway, this episode highlights how advanced imaging is uncovering new insights into neuroinflammation and viral-driven disease including implications for cancer biology and long-term brain health.
