A study of 10 patients at Oxford University used xenon gas during MRI scans to identify lung damage not picked up by conventional scans. This technique was developed by a research group at the University of Sheffield led by Prof James Wild. Lung experts said a test that could spot long-term damage would make a huge difference to Covid patients.

This technique was carried out on 10 patients aged between 19 and 69 years. Eight patients had persistent shortness of breath and tiredness three months after having Covid-19, even though none of them had severe condition and conventional scans were normal.

This novel scanning technique showed signs of lung damage - by highlighting areas where air is not flowing easily into the blood in the eight breathlessness patients. The researchers want to plan a trial in 100 patients to discover lung damage in wider age group and less severe cases.

The researcher adds that In other fibrotic lung diseases the methods are very sensitive to this impairment and they hope the work can help understand Covid-19 lung disease better.
