Computed tomography 3D rendering of the lungs of a person who is recovering from Covid-19. There are no visually apparent abnormalities in the blood vessels. Using special tools, however, researchers at NHLBI are making progress in analyzing the vascular structure of the lungs in a way that reveals hidden impairments in the gas exchange capacity of post-Covid lungs. The findings could help doctors evaluate how blood vessels change in long Covid (https://www.nhlbi.nih. gov/covid/long-covid) and might lead to new ways to diagnose and treat the condition.
