Covid-19 could be causing lung injury still detectable more than three months after patients are infected, researchers suggest
An investigation of 10 patients at Oxford University utilized a novel filtering strategy to distinguish harm not got by ordinary outputs.
It utilizes a gas called xenon during MRI outputs to make pictures of lung harm.
Lung specialists said a test that could spot long haul harm would have an enormous effect to Covid patients.
The xenon procedure sees patients breathe in the gas during an attractive reverberation imaging (MRI) examine.
Prof Fergus Gleeson, who is driving the work, evaluated his filtering strategy on 10 patients matured somewhere in the range of 19 and 69.
Eight of them had steady windedness and sluggishness three months in the wake of being sick with Covid, despite the fact that none of them had been admitted to serious consideration or required ventilation, and ordinary outputs had discovered no issues in their lungs.

The sweeps gave indications of lung harm - by featuring regions where air isn't streaming effectively into the blood - in the eight who revealed windedness.
The outcomes have incited Prof Gleeson to design a preliminary of up to 100 individuals to check whether the equivalent is valid for individuals who had not been admitted to medical clinic and had not experienced such genuine indications. He is wanting to work with GPs to examine individuals who have tried positive for Covid-19 over a scope old enough gatherings.
The point is to find whether lung harm happens and if so whether it is lasting, or settle after some time.
He stated: "I was expecting some type of lung harm, however not to the extent that we have seen."
The danger of extreme ailment and passing increments notably for the over 60s. Yet, on the off chance that the preliminary finds that the lung harm happens over a more extensive age gathering and even in those not expecting admission to clinic "it would move the goal lines," as indicated by Prof Gleeson.
He accepts the lung harm distinguished by the xenon sweeps might be one of the elements behind long Covid, where individuals feel unwell for a while after disease.
The filtering method was created by an exploration bunch at the University of Sheffield drove by Prof James Wild who said it offered a "interesting" method of demonstrating lung harm brought about by Covid-19 disease and its eventual outcomes.
"In other fibrotic lung sicknesses we have demonstrated the techniques to be touchy to this hindrance and we trust the work can help comprehend Covid-19 lung infection."
