BERLIN : Using a novel technique which enables high resolution imaging of damaged lung tissues, scientists have found the changes caused by severe COVID-19 in the structure of the organ's blood vessels and air sacs, findings that may support the development of new treatment methods against the disease.In the study, published in the journal eLife, the scientists developed a new X-ray technique which enables high resolution and three-dimensional imaging of lung tissues infected with the novel coronavirus SARS-CoV-2.Using the new method, the researchers, including those from the University of Gottingen in Germany, observed significant changes in the blood vessels, inflammation, and a deposition of proteins and dead cells on the walls of the.
