Researchers In The UK Identify Persistent Damage To Lungs In COVID-19 Patients

The 129Xe MRI is pinpointing the parts of the lung where the physiology of oxygen uptake is impaired due to long standing effects of COVID-19.

A study conducted by Sheffield and Oxford researchers in the UK has identified long-term effects of Covid-19 on lungs using a cutting-edge method of imaging.

The research has revealed that lungs of the patients didn’t recover fully even after three months of their discharge from the hospital. In some cases the duration is even longer.

“Patients who have not been hospitalised with COVID-19 but who are experiencing long-term breathlessness may have similar damage in their lungs, and a larger study is needed to confirm this”, a release by the Sheffield University said on Wednesday.

The research has been published in Radiology, the world’s leading radiology journal.

Lead author of the study, Professor Jim Wild, Head of Imaging and NIHR Research Professor of Magnetic Resonance at the University of Sheffield, said, “the findings of the study are very interesting.

The 129Xe MRI is pinpointing the parts of the lung where the physiology of oxygen uptake is impaired due to long standing effects of COVID-19 on the lungs, even though they often look normal on CT scans.

“It is great to see the imaging technology we have developed rolled out in other clinical centres, working with our collaborators in Oxford on such a timely and clinically important study sets a real precedent for multi-centre research and NHS diagnostic scanning with 129Xe MRI in the UK,” the release quoted him as saying.

The study’s Principal Investigator Professor Fergus Gleeson, Professor of Radiology at the University of Oxford and Consultant Radiologist at Oxford University Hospitals (OUH) NHS Foundation Trust, said: “Many COVID-19 patients are still experiencing breathlessness several months after being discharged from hospital, despite their CT scans indicating that their lungs are functioning normally.
