Lung damage caused by COVID-19, latest study show

Washington, Dec 1(UNI) Latest studies have shown that COVID-19 can cause abnormalities in the lungs still detectable more than three months after patients are infected, scientists have said.
A study of 10 patients, aged between 19 and 69, at Oxford University used a novel scanning technique to identify damage which were not picked up by conventional scans, BBC reported.
The technique used a gas called Xenon during MRI scans to create images of lung damage.
Lung experts said a test that could spot long-term damage will help make a huge difference to COVID patients.
The Xenon technique sees patients inhale the gas during a magnetic resonance imaging (MRI) scan.
Eight of them had persistent shortness of breath and tiredness three months after being ill with coronavirus, even though none of them had been admitted to intensive care or required ventilation, and conventional scans had found no problems in their lungs.
The scans showed signs of lung damage - by highlighting areas where air is not flowing easily into the blood - in the eight who reported breathlessness.
The results have prompted a trial of up to 100 people to see if the same is true of people who had not been admitted to hospital and had not suffered from such serious symptoms. Plan are to work with GPs to scan people who have tested positive for Covid-19 across a range of age groups.
The aim is to discover whether lung damage occurs and if so whether it is permanent, or resolves over time.
