MRI links long-COVID brain fog to lung function
By Will Morton
MRI shows that lower pulmonary gas exchange in the lungs of long-COVID patients may be associated with cognitive symptoms.
November 26, 2024
Individuals in the study were plotted with the x-axis being rank of pulmonary gas exchange. The black dots show the pulmonary gas exchange ratio (red blood cell to tissue plasma ratio, RBC:mem) on the left y-axis and the blue dots are the cognition scores on the right y-axis. Gas exchange maps of three representative patients from a low, medium, and high pulmonary gas exchange. Image courtesy of RSNA.
