New Imaging Technique Starkly Reveals The Source of Long COVID in The Lungs

The vascular damage is reflected by the MRI scans; CT scans also confirm the abnormalities in the finest blood vessels in our lungs.has already demonstrated a shift in blood distribution from smaller to larger blood vessels within the lungs of hospitalized COVID patients.

The team proposes several potential mechanisms for the alteration in gas exchange they witnessed, illustrated in the diagram below.The vessels may be losing their flexibility which reduces how much blood is available for xenon to bind to , new blood flow patterns thanks to changes in vessels elsewhere may be shunting the blood away from the gas exchange regions , or there is a physical blockage preventing the blood from getting there .

Matheson and colleagues caution that the small sample size limits their ability to generalize, but urge for further investigation. And whatever the mechanism behind this is, it is starkly clear catching the virus can really mess with the circulatory system.
