ALB and edema: Our promising Cy7-albumin 3D OI/CT results prompted us to see if we can develop a translational PET scan to visualize albumin distribution in diseases that have increased lung permeability, including ARDS, COVID-19 pneumonia, blood-borne sepsis, primary lung infection, gastric aspiration, barotrauma, transfusion associated acute lung injury and hydrostatic chronic heart failure associated pulmonary edema.
