Novel dynamic imaging technology captures the body's immune response to COVID-19 infection

A team of UC Davis scientists used dynamic total-body positron emission tomography (PET) to provide the first imaging of the human body's immune response to COVID-19 infection in recovering patients. Their work, published in Science Advances, could lead to a better understanding of how the body's immune system responds to viral infections and develops long-term protection against re-infection.
